TVS Apache RTR 180 ABS

Overview of TVS Apache RTR 180 ABS
TVS Motors have launched the Apache RTR 180 ABS in Indian market. This is the first Indian bike to feature ABS (Anti-lock Braking System). In terms of looks it is almost same like the regular Apache 180 except new stickers and decals. It has been priced at Rs.9000 more than the non-ABS version. The Apache RTR 180 ABS is available in only white shade with orange decals. The bike is available at TVS dealerships across the country.
Technical Highlights of TVS Apache RTR 180 ABS
Anti-lock Braking System technology is an integration of a HECU (Hydraulic Electronic Control Unit) and Independent Wheel Speed Sensors which help determine when a wheel is likely to get locked. When the brakes are applied hard, the wheel tends to lock. At this point, the HECU takes over instantaneously and modulates the brake pressure continuously to keep the Apache RTR 180 ABS in the most effective braking zone while ensuring precise maneuvers.
Sensors on the front and rear wheels independently monitor the speed of rotation at all times and can sense the risk of wheel lock whenever the brakes are applied. If the sensors communicate an impending wheel lock, the HECU modulates the braking pressure and prevents it, therefore reducing the risk of the rider losing control of his Apache. When the ignition is turned ‘ON’, the Apache RTR 180 ABS does an automatic self-check, which is indicated by the blinking of an LED on the console and the speed sensors monitor the wheel speed and send signals continuously to the HECU.
The Apache RTR ABS is also equipped with Rear Wheel Lift-off Protection  (RLP) system which regulates deceleration when the bike is likely to lift off during emergency braking situations and takes over control, with no loss of stopping distance. With the RLP system continuously monitoring and controlling the braking, the bike gives the best stopping performance. The bike comes with an ‘ABS-Off’ switch, which disables the ABS technology, enabling the rider to showcase his capabilities on the Apache RTR, in controlled conditions. In an effort to enhance the ‘thrill of biking’ in the TVS Apache RTR 180, the company has fitted the bike with an all-new 3 phase Full DC lighting system and an efficient energy management system.
Official Statement by Mr. Murali Srinivasan, General Manager
“With this new, compact motorcycle Antilock Braking System (ABS), which has been developed by Continental’s Chassis and Safety Division in collaboration with TVS Motor Company, we have further strengthened our presence as a strong international supplier in the Indian automotive industry. ABS for motorcycles emphasizes our philosophy of ‘Intelligent mobility and safety for everyone’. It is a vital and decisive step on the road towards “Vision Zero,” when safety is evolved to such a level that there are no more serious accidents on the road. In view of globally available technologies, safety is non-negotiable. It is gratifying for Continental that we have associated with an Indian manufacturer to give India her first motorcycle with ABS technology,” Mr. Murali Srinivasan, General Manager (Chassis and Safety Division), Continental said.
Engine & Performance Figures Of Apache RTR 180 ABS
The Apache RTR 180 ABS is powered by the same 177.4cc engine which generates 17 Bhp of maximum power with 15.5 Nm of maximum torque. The new 177.4cc mill is a bored out variation of the 160cc mill, and has a longer stroke too. The peak power is produced at 8500 rpm, similar to RTR 160, though the peak torque is now produced at 6500 revs. The aerodynamic air scoops add to the design plus it ensure Air is directed towards the engine unit to help better cooling efficiency. TVS claims the new apache RTR 180 to reach 60kmph from standstill in 4.15 seconds and top speed as 125kph.
Looks & Styling Of Apache RTR 180 ABS
The TVS Apache 180 ABS adorns a new graphic scheme to distinguish itself from its smaller siblings, with RTR emblazoned boldly on the tank scoops. The front forks and the gas reservoirs for the rear shocks are now painted in a new golden shade and the clip-ons have a new RTR 180 emblem at the centre. Stylish alloys, unique grab rails, classy silencer, larger & sharp lined fuel tank, all these elements combine perfectly to give Apache RTR 180 ABS a sporty eye-catching looks. Apart from the New White tachometer the rest of the instrument cluster is same like the RTR 160 with Digital blue backlit Speedometer. The rear is also same with LED tail lamps, re-styled silencer and CBZ X-treme type split grab rail.
Ride & Handling Of Apache RTR 180 ABS
New Apache RTR 180 ABS's wheelbase is longer than the old Apache RTR 160 by a good 40mm, making it substantially more stable and confidence inspiring than its earlier iteration when leaned over. RTR 180 ABS feels more stable and planted both in straight line as well as around bends. The engine fairing design shows the amount of detailing gone into its development plus add into aerodynamic design.
It employs a forged brake lever and gear lever set which delivers great looks and also lighter in construction. It also comes with removable rear fender - a first in its class. The riding posture on the RTR 180 ABS is forward set up one which brings a huge difference in ride quality. A pillion rider will also feel more comfortable sitting on a RTR ABS because of its forward set foot pegs and elegantly designed unique grab rails. RTR's specially developed race crouch mirrors provide better angle and safety besides looking great too.

Aprilia MANA 850 ABS

The Aprilia Mana is the state of the art in motorcycle technology. Only Aprilia, with its legendary technical skills, would have dared take on a challenge of this entity. The Aprilia Mana 850 is so advanced and so unique that it simply cannot be compared with any other motorcycle. The Mana takes all the stress from motorcycling while injecting more satisfaction and more fun into riding under all conditions, from commuting to sports touring on the open road. All you need to do to enter a whole new world is press the button on the handlebars.
Its revolutionary Sportgear transmission is electronically controlled to deliver unrivalled riding pleasure. So whatever your riding style, and whatever the road conditions, the Mana is the bike you will want to be on.
The transmission management system offers a choice of three “Autodrive” mappings plus a manual, seven speed, sequential gearshift, so you can be absolutely certain to find the perfect ratio for any traffic condition and riding preference. Whether you are just nipping across town or blowing away the cobwebs on a winding country road, the Aprilia Mana always delivers the ideal response and the same unique riding satisfaction. Whatever the conditions, and whoever the rider (even the most demanding), the Mana guarantees a perfect, peak-efficiency ride that lets you discover hitherto unknown potential.
The Mana’s compact, sporty and ecological 90° V twin engine is the perfect partner for this type of transmission. It is compact, powerful and ecological. Pace-setting power and torque mean brilliant performance, especially in acceleration. Virtually no other naked can keep up with a Mana as it pulls away from the lights! Yet the Aprilia Mana 850 is so amazingly easy to ride that blistering performance is well within the reach of any rider. The technology that Aprilia has developed for the Mana 850 is truly ‘rider-friendly’ and amazingly easy to use. The clutch lever has gone, replaced by an electronic control system that leaves you free to relax and enjoy the ride. The sequential gearshift can even be operated by a simply handlebar control as well as by the classic pedal.
As with all Aprilias, accurate design of the chassis guarantees top level handling. The Mana 850’s tubular trellis frame gives the bike impressive strength and torsional rigidity, and a single piece aluminium swingarm and advanced suspension delivers road holding to satisfy even the most demanding sports rider. Top quality brakes add to active safety by ensuring impressively short stopping distances.
The following are the characteristics that make the Aprilia Mana unique:
• 90° V twin engine with four valves per cylinder, Euro 3 homologated;
• sportgear transmission: electronically controlled sequential gearshift offering two shift modes seven speed manual or Autodrive with three mappings: Touring, Sport, and Rain
• storage compartment with non-scratch lining, large enough for a full-face helmet, with mobile phone holder, toolkit & document holder, and 12V power socket;
• under-seat fuel tank;
• brakes with radial calipers;
• 43 mm upside down fork;
• offset monoshock with spring preload and rebound adjustments;
• steel trellis frame with single piece aluminium swingarm;
• twin spark ignition;
• electronic fuel injection with single throttle body;
• latest generation two channel ABS system (ABS version only)

DESIGN
With its exclusive, unmistakably Italian styling, the Mana 850 embodies the perfect combination of elegance and practicality. As with all Aprilia nakeds, the Mana’s high-tech components make an essential contribution to overall design. 

The 16 litre tank is located under the seat, lower than normal, to distribute weight more evenly and lower the bike’s centre of gravity. The “traditional” tank location is occupied instead by an illuminated storage compartment that is lined with non-slip, non-scratch material and big enough to house a full face helmet. The compartment also incorporates mobile phone storage and a 12V power socket. 
The Mana is the first motorcycle ever to provide fully integrated helmet storage, a unique and immensely practical advantage, especially for urban commuting and short trips. The compartment is opened electrically by a convenient switch on the handlebars. The lid opens under the control of a hydropneumatic damper that prevents accidental opening while the bike is in motion. A manually operated lever under the passenger seat is provided to release the compartment lid in the event of a flat battery.
ENGINE
There can be no doubt that the Mana engine has opened new horizons in the world of motorcycling, featuring as it does a twin cylinder layout, electronic fuel injection, bags of torque, and above all a revolutionary transmission system that completely replaces the conventional mechanical gearbox and delivers a whole new motorcycling experience even under sport riding conditions.
To develop this amazing new engine, Aprilia has relied on the expertise of the world’s top designers and all the skill of its own R&D department.

Mana: the future of the gearbox
The most interesting aspect of the Mana engine is without a doubt its primary drive system, based on an electronically controlled, sequential transmission that offers the rider a choice of control modes.
Riders can choose from two options:
- Sequential mode: The rider decides for himself when to change gear, either using the conventional pedal or a switch on the handlebars. A servo mechanism shifts the main pulley to change between the seven gear ratios amazingly quickly. During deceleration, if the rider omit to change gear manually, the control system intervenes to change down automatically, preventing engine speed from dropping below the set threshold and providing another valuable aid to active safety.

- Fully automatic mode (Autodrive): Sophisticated electronics assume control over everything, and the CVT transmission keeps the engine running at maximum torque speed for optimum pickup and acceleration. The Sportgear transmission offers a choice of three mappings:
Touring: for minimum consumption and maximum usability.
Sport: for top performance with blistering acceleration
Rain: for use on wet or slippery roads

- Semi-Autodrive mode allows the rider only to change down independently. This is particularly useful for overtaking at maximum torque revs or for boosting engine braking when riding down a hill.
You can switch from Autodrive to Sequential mode and back at any time, irrespective of riding conditions. The handlebar gearshift control can also be disabled from the dashboard.

The 90° V engine, chosen for torque and power delivery, is the perfect match for this type of transmission. Delivering 76 horsepower at the crank and well in excess of 7 kgm of torque (at 5,000 rpm), the engine produces an extremely flat power curve that translates into plenty of ready power even at low revs.
FRAME
The robust steel tube trellis frame sets new standards for this class of machine and ensures top level handling in line with the characteristics of the innovative engine. The single piece aluminium swingarm is damped by a monoshock that is laterally offset to free up space for the exhaust pipe behind the engine and make the motorcycle more compact. The Mana has a wheelbase of only 1,463 mm, extremely short for a naked, even a sports model.

SUSPENSION
The 43 mm upside down fork slides easily and features an optimised setup for excellent performance even under sport riding conditions. 120 mm of front wheel travel lets you tackle all sorts of road surface.

BRAKES
Impressive stopping power is delivered by the very best braking technology currently available, developed in-house by Aprilia. Radial calipers with 4 pistons are the state of the art for motorcycle brakes and ensure maximum active safety under all braking conditions. The generous front discs are 320 mm in diameter, the standard size for Aprilia’s big bikes, and are complemented by a single 260 mm rear disc.
A sophisticated two channel ABS system maximises the Mana ABS’s already impressive levels of active and passive safety by preventing wheel lock on slippery surfaces and improving braking performance.

ACCESSORIES
Your Mana 850 can become even more versatile, exclusive and unique with the dedicated accessories that Aprilia has designed to satisfy all your needs, from around-town commuting for work or shopping to weekends away and even long journeys.
Adjustable windscreen for stylish protection in all weathers, even at high speeds. Generous side cases personalised with the Mana logo, City 35 litre top box with matching paint finish cover and passenger backrest, robust steel luggage rack for an extended carrying capacity and perfect weight distribution.

Aprilia RSV4

A revolutionary project and a unique history of victories on the racetrack have come together to create the RSV4. A supersport with absolutely exclusive racing technology, developed around the 4 narrow V cylinder engine developed from the technical know-how that has led Aprilia to victory on racetracks all over the world. Aprilia RSV4 hits the racetrack and the roads with one goal only: to win.
33 championships, 254 MotoGP World Championship wins and 8 Superbike victories : over the last two decades Aprilia has become a modern motorcycling legend. The bikes from Noale have dominated tracks the world over thanks to the genial design, courage and extraordinary abilities of the technicians who pursued innovative solutions by experimenting, innovating and sometimes revolutionising technical schemes that seemed to be unchangeable. Aprilia RSV4 Factory, the bike that brings Aprilia back into the 2009 Superbike World Championship, is the product of this immense technical know-how. It is a highly technologically advanced motorcycle, conceived for racing and for this purpose designed and developed by Aprilia together with the marque's Race Division, the largest and most advanced of its kind in Europe and one of the most important in the world.
Aprilia RSV4 Factory is a racing machine that, in line with the Aprilia tradition, follows a completely innovative approach in its design and construction. Its narrow V engine, the use of state-of-the-art electronics,plus its lightness and extreme compactness are only a few of the features that make it unique in the world. Aprilia RSV4 Factory is designed and built with the same philosophy adopted by the Aprilia race division. This is why RSV4 Factory is the most “complete” Superbike racing replica, ready for those who want to venture onto the track with a class leading motorcycle.

The engine of the RSV4 Factory is the most innovative and powerful Aprilia has ever built. It is a super compact 999.6 cc 65° V-four cylinder engine designed for maximum power (180 CV), where powerplant engineering comes together with the finest materials and the most advanced electronic control solutions. Aprilia's engine, in fact, uses a Ride by Wire multimap technology, a solution that opens up new frontiers for engine management, with practically infinite possibilities for further development.

Besides the triple map Ride by Wire system, a sophisticated electronic injection system with two injectors and adjustable height ducts are fitted.

Aprilia RSV4 Factory is an absolute supersport motorcycle, the most complete bike available on the market for bike fans, and its chassis confirms this: designed for the racetrack, it has adjustment features that are typical of racing motorcycles. The adjustable geometry chassis allows parameters such as the position and inclination of the headstock, the height of the swingarm pin and even that of the engine to be changed. The construction technology is also motorsports-derived: the RSV4 Factory chassis and swingarm are made of aluminium with variable section castings and pressings.

The components are the state-of-the-art in motorcycling technology: Öhlins Racing fork, rear monoshock and steering damper, Brembo monobloc callipers, forged aluminium rims.

Aprilia RSV4 Factory is the new benchmark in the street legal superbike sector. The unique characteristics of the bike are listed as follows:

- Compact, innovative design
- New - and unique - 65° V-four cylinder engine
- Multi-adjustable perimetral aluminium alloy frame
- Adjustable engine position relative within frame
- Asymmetric aluminium swingarm
- Öhlins Racing full adjustable fork and rear monoshock.


DESIGN. The quest for ultimate compactness

Creating the most compact, innovative and gorgeous supersport bike on the market: a tough and intriguing challenge for Aprilia's style department! This is how RSV4 Factory was created, a motorcycle that sets new performance and riding standards while opening new horizons in ultra-sports motorcycle design. Just a few simple and distinctive styling elements highlight rather than conceal the specific technical features of the Aprilia RSV4 Factory. Its frame and engine stand out as fundamental elements of the motorbike's design.
In line with Aprilia traditions, the design of RSV4 Factory does not focus merely on looks but it serves technology and performance. Every detail has been conceived not just to be unique and beautiful, but also and above all to be efficient.
The needs of the optimised dynamic intake system feeding the V4 defined the strong-charactered front, with extra-large air intakes that not only develop considerable overpressure in the airbox (approx. 35 mb @ 280 km/h), but also completely separate the headlamps from the bottom of the fairing. This results in an absolutely unique style, never seen before on a sports motorcycle. The look of the RSV4 Factory is absolutely original, technological and definitely aggressive. The triple headlamp cites the original Aprilia maxi sportsbike, that RSV that set new standards for sports twins in 1998.
Smaller, lower and narrower than any 4 cylinder bike before,the RSV4 Factory's extreme compactness is its strength, together with an almost obsessive pursuit of perfect ergonomics (crucial for perfect riding control), which has always distinguished Aprilia's road and World Championship dominating motorcycles.
In depth aerodynamic studies minimised surfaces without compromising the bike's class-leading aerodynamics. The spectacular, ultra-compact tail fairing is one of the most distinctive features of this motorcycle. The LED taillight merges stunningly into the tail, offering excellent luminosity. Even the rear of the RSV4 Factory is absolutely unmistakable.


ENGINE. An exclusive 65° V4

The pursuit of maximum engine performance in a supersport motorcycle must be accompanied by a perfectly positioned engine in the frame. Mass centralisation, swingarm length and optimum weight distribution are ingredients for achieving the most competitive bike, together with the pursuit of maximum power and perfect power delivery.
Aprilia engineers have known for years that a narrow V engine layout is the ideal technical solution for obtaining a class-beating chassis architecture that emphasises the performance of the engine. It is no coincidence that the RSV 1000 twin, launched in 1998, is still universally acknowledged as the sports motorcycle with the best chassis ever. Even the multiple race-winning RSA 250 GP motorcycles (5 world championship victories in the last three seasons) produced by Aprilia's race division have a V engine. Aprilia was able to draw from its extensive expertise gained in years of unrivalled supremacy in the Motorcycle World Championship; hence, when the time for defining the new Superbike came, after evaluating all possible solutions, a narrow V engine was chosen. A 65° V-4 cylinder engine, the only solution that could ensure unparalleled performance, enabling the outstanding chassis architecture that has defined all Aprilia racing motorcycles for the past twenty years.
Besides the exclusive configuration that makes the 65° V4 unique around the world, the technical advantages of the Aprilia four-cylinder engine can be summarised as follows:
- Perfectly integrated into the frame, with optimal mass centralisation and minimised inertia for benchmark agility.
- Absolute slimness, its overall width is comparable to that of a twin cylinder motorcycle, with huge benefits in terms of ergonomics and aerodynamics.
- The compactness of the engine makes a very oversquare cylinder layout possible, using large bores and subsequently larger valves, helping the engine breathe more freely and achieve higher engine speeds (14,000 usable rpm).

The engine was entirely developed by Aprilia's Research and Development Division, aiming at offering record performance and ridability in compliance with the strictest reliability and quality standards.

Aprilia's V4 design exploited the most powerful calculation programmes currently available on the market, resulting in a highly optimised engine layout. By slightly opening the angle of the V (with respect to a 60° V engine), the designers could make use of the larger space to optimise the inlet ducts and maximise engine efficiency. The RSV4 engine has class-leading fluid dynamics attributes that no narrow V engine can match.

The unique timing system makes extremely compact heads possible (measuring only 250 mm high at the rear), especially in the area beneath the frame spars, which are thus much narrower than would otherwise be possible. The lateral timing chain drives the intake camshaft only and follows an optimised path for improved timing precision and chain durability.


A gear pair at the centre of the cylinder bank transmits drive to the exhaust camshaft. This solution made it possible to obtain an extremely compact head in the exhaust area. The V4 is even more compact than the V60 Magnesium twin mounted on the RSV 1000 R.

A countershaft dampens vibrations even more than in a 90° V engine. The crankcase is a monobloc configuration with integrated cylinder liners for maximum rigidity and consistent performance.

Electronics of the Future

Aprilia's RSV4 Factory engine features full Ride by Wire technology. There is no direct connection between throttle grip and the throttle valves, which are completely controlled by a latest generation Marelli control unit.
Each bank has a dedicated servo unit actuating the two relevant throttle bodies only. Hence the two banks, and subsequently the quantity of fuel injected, can be managed independently. While this solution has been tried and tested by Aprilia, it has never been applied before on such a powerful engine, thus opening up practically infinite possibilities for power delivery control. This technology immediately benefits the rider who, thanks to the triple mapping that can be controlled directly from the handlebar, can change the engine delivery mode and thus the motorcycle's temperament at any time.

The fuel supply uses two injectors per cylinder:one injector is placed downstream of the throttle valve and a "shower" injector is placed in the airbox and starts working at high loads and revs. The technological excellence of the V4 engine is complemented by electronically controlled variable length intake ducts. At low revs and loads, the long duct favours torque and smooth power delivery. When top performance is required, the upper part of the intake duct raises, thus shortening the duct and leaving the engine free to express its full power potential. A butterfly valve in the exhaust further optimises power delivery.


The transmission was also designed according to the most advanced criteria. To underscore the racing soul of the V4 engine, a cassette gearbox is used, with a multiplate wet clutch disc equipped with a mechanical slipper system to optimise engine braking torque and ensure stability under hard braking.

Lastly, in order to minimise weight, Aprilia's new engine makes large use of ultralight materials; all valve covers and external housings are made from magnesium.

The V4 engine in short:

Engine capacity: 999.6 cc
Architecture: 65° V4
Power: 180 HP (132.4 kW) at 12,500 rpm
Crankcase: monobloc with integrated cylinder liners
Timing system: 4 valves per cylinder (Titanium and Nymonic) operated directly by a camshaft driven by a mixed chain/gear system (lateral timing chain, central gear train)
Fuel system: Magneti Marelli electronic injection with 2 injectors per cylinder and integrated independent Ride by Wire system for each bank. Three mappings selectable from handlebar. Electronically controlled variable length intake ducts
Antivibration countershaft
Maximum rpm: 14,100 rpm
Compression ratio: 13:1
Transmission: 6-speed direct-control cassette gearbox
Clutch: multiplate wet clutch with mechanical slipper system
Exhaust system: 4 into 2 into 1 headers with oxygen sensor and single silencer with integrated catalytic converter and butterfly valve.


CHASSIS. Aprilia's entire racing know-how

A unique engine like Aprilia V4 could be nothing but combined with an extraordinary chassis that stresses the uniqueness of this motorcycle. Years of races and victories at the top level melts into a racing chassis implemented by Aprilia's research and development department, with construction solutions and adjustments that only racing prototypes can boast.
RSV4 Factory reaps the rewards of Aprilia's entire racing experience.

Perfect mass centralisation was a must when the RSV4 Factory frame was being developed. Everything was designed in order to achieve the best possible result, starting from the tank position (crucial for riding) with most of the fuel under the saddle in order to optimise motorcycle balance and eliminate any riding differences between full and empty tank.

There is no doubt: Aprilia RSV4 Factory is a true track-ready motorcycle, and a front/rear weight distribution of 52/48 confirms this.

Frame

In line with Aprilia race division traditions, the RSV4 structure uses castings and aluminium pressings that are welded to create a far more rigid frame than that of the RSV 1000 twin, which was already a benchmark. In particular, torsional and flexural rigidities were optimised in order to offer perfect feeling and control as well as the ability to handle high power outputs such as those of the Superbike version.

Notwithstanding the higher performance, the RSV4 Factory frame weighs almost the same as the RSV, at only 10.1 kg, a lightness matched only by racing frames. The special construction technology also allows both the frame and the swingarm to show the natural and shining colour of the aluminium, which makes the appearance of the RSV4 Factory very similar to that of a racing prototype.


Designed using the knowledge acquired during GP racing, the spectacular swingarm of the RSV4 Factory, like its frame, is made by combining castings (the internal part and the swingarm pin/wheel connection areas) with aluminium bent sheet elements (the external part) to form a very rigid but super light box section capable of minimising the moving masses, exalting the reactivity and sensibility of the motorcycle to the suspension adjustments. The asymmetric conformation, with an arch section on the right side and a reinforcing arch on the left, made it possible to implement an exhaust system with optimised internal volumes without penalising the rigidity of the swingarm. Here too, FEM modelling was used in the design process to optimise cross sections and thicknesses. The swingarm of the RSV4 Factory weighs only 5,100 grams, close to the absolute standard threshold for this technical element.


The desire to offer the first four V cylinder "race ready" superbike in the world led Aprilia to find unique solutions that will hardly be found on competitors' bikes even in the years to come.

In order to boost chassis performance and make it match the rider's style and wishes, or features of the track, Aprilia RSV4 Factory ensures a combination of adjustments that are pretty much infinite. The multi-adjustable suspensions, taken for granted on a motorcycle of this level, are combined with adjustments of the headstock position and rake (through interchangeable bushings), the rear end height, the swingarm pin height and - introducing a new capability exclusive to this bike - the engine position in the frame.
Aprilia RSV4 Factory is the most highly adjustable production motorcycle in the world, just like a real race bike.

Suspension

The Öhlins Racing upside-down fork has 43-mm stanchions and is titanium nitride coated to minimise friction. The wheel travel is 120 mm. Like in race motorcycles, the fork allows precision adjustment for hydraulic compression and rebound damping and spring preload.
The Öhlins Racing rear shock absorber is equipped with a “Piggy Back” nitrogen canister and can be adjusted for spring preload, compression and rebound damping and length, thus allowing the height of the rear end of the bike to be changed to adjust the set-up to the different riding styles and tracks. The wheel travel is 130 mm.
The motorcycle is also equipped with an Öhlins Racing adjustable steering damper.

Brakes

The front system is without a shadow of a doubt the best system available on the market. Brembo monobloc radial callipers are the state-of-the-art in racing braking systems thanks to their power, high modulability and fatigue resistance.
The dual 320-mm diameter stainless steel floating discs are completely new and were developed by Aprilia specifically for this motorcycle. A rotor with reduced height and asymmetric perforation were used, allowing the braking power to be improved and the front wheel to be lightened by approximately 500 grams. The floating retainer is fastened to the flange with 6 pins only in order to minimise inertia and weight.
The brake pump is the radial type to improve lever feel and response accuracy. The rear braking system is Brembo “Serie Oro” with 220-mm diameter stainless steel disc and two-piston caliper, with racing-type pump and integrated tank.

Rims

The search for greater lightness led to implementation of new forged aluminium rims. The original design further decreases the weight (approximately 1 kg less than the RSV 1000 twin) which, together with the new brake discs, minimises unsprung mass and rotating mass inertia, benefiting motorcycle responsiveness.

Components

A real Superbike is special not only as far as performance is concerned but also for the care it is built with. With regard to the RSV4 Factory, the details say it all: no other "race ready" motorcycle has ever been built with such care. The attention paid to its construction not only satisfies the desire for beauty (a motorbike built like RSV4 Factory is in any case gorgeous), but most of all aims at achieving the goal: to win. This is why every detail was thought out to increase performance and functionality, reducing the weight and considerably increasing the product's quality and finish.

The following components are worth pointing out:

- Instrument panel: the mixed type (digital-analogue), it receives all the information from the CAN line and becomes an integral and crucial part of the self-diagnosis system as it is fitted with memory. It is a real onboard computer, fitted with a dot matrix display inserted in a minimal, extremely modern and compact design that provides all the information relating to the use of the motorcycle, including: shift light, engaged gear indication, indication of the engine map being used and chronometer with time storing memory. Its functionality was improved to reach a level that is even better than that of the best products available on the market, all use modes are controlled from the left hand switchgear unit so the hands can always remain on the handlebar.

- the front headlamp uses three elements that call to mind of the first RSV 1000 twin, proving to be perfectly integrated, even from the structural point of view, with the top fairing and creating a very distinctive front. The parabolic mirror was designed with modern calculation systems that led to an excellent result: maximum visibility at night with reduced weight and size.


- The electrical system was designed in order to achieve maximum functionality, rationality and minimum weight: the result is an extremely clean and compact layout that makes maintenance operations easier and is preset for use on the racetrack as the parts dedicated to the headlamps can be easily removed. Even the turn indicators - with the front indicators incorporated in the rear view mirrors and the rear indicators in the license plate holder – can be removed quickly for use on the track, the real hunting ground of Aprilia RSV4 Factory.

Bajaj Pulsar 250 CC Will Have Single Cylinder Engine

Bajaj has been doing great with its Bajaj Pulsar range of bikes in India. It’s one of the high selling bikes in India and is quite popular especially with youth in India. We brought you a story about Bajaj Pulsar 250Kawasaki Ninja 250R however seems to be the bike which matches the specifications which were suspected to be of Pulsar 250 back then. CC back in March 2010. Eventually it has come out to be a different bike. As per some ancillary sources, Bajaj was about to sell a 2 cylinder 250 CC bike in India, which was mistakenly identified to be a Pulsar. The truth is that the two-cylinder engine pulsar has not been on Pulsar product range so far.
As per the recent information, Bajaj will soon be launching a 250 CC single cylinder variant of Bajaj pulsar to compete with the Honda CBR250R and other 250 CC performance bikes scheduled for launch in the year 2011. One such expected launch is Yamaha FZ250 which may come around mid 2011.

Bajaj-KTM Street Bikes To Be Launched In India Soon!

There have been many rumors regarding the collaborative product but recent official talk about the bikes is that the price-tag of the motorcycle will be over ₹ one lakh. The range of street bikes will feature engines of capacity 125cc and more. The launch is somehow definite in the cities of Europe by the end of this year and the welcome season of 2011 will be the time for India to host some launches from the team. Bikes will be sold through Bajaj Autos Pro-Biking showrooms.
It is news that the first launch from Bajaj-KTM will have a price tag over ₹1, 00,000. But not sure whether that bike will have an engine of 125cc or over 200cc. That shall continue remaining mystery for we people. Hope to see much powerful and superior bikes over those which we have we have already available in the market these days.
Another news from the team is that they are going to launch a series of imported bikes from KTM in Indian market in the upcoming years. This will definitely boost competition with Kawasaki which is looking to launch powered bikes in Indian market. The only similarity between Kawasaki and KTM will be the partner Bajaj Autos, India

Gold plated chopper qualifies for world’s most expensive!

When hearing about the world’s most expensive chopper you usually get the “what, is it gold plated?” reaction and we can understand the irony, but it seems that someone did think at gold plating a chopper with 24 karats gold and ask $500,000 for it. The thing does look like a work of art, but we wouldn’t go as far as calling it a jewel. Isn’t this too much?

RSR FUEL CALIBRATION

The most difficult aspect of tuning whether it is fuel injection or carburation is getting the fuel delivery curves exactly right for your application. In the case of fuel injection this means getting your base map exactly correct for the various combinations of manifold pressure and engine rpm. RSR provides you with the tools necessary to completely map your engine. We realize that you do not have a $200,000.00 computerized dyno facility or a $10,000.00 exhaust gas analyzer. Our AUTOCAL software gives you both digital and analog read-outs of air/fuel ratios and engine load factors to speed your developmental process. You can manually edit point by point your base fuel map using these digital and analog read-outs or you can use the autocalibration mode and let the electronics write your base map during actual driving or dyno runs. By using the autocalibration mode and fine-tuning individual points in the manual edit mode you will be able to make a fuel map perfectly suited for your particular application. If you are unable to use a portable PC while the vehicle is moving we offer an inexpensive portable onboard readout of real-time air/fuel ratios and a booklet showing you how to use this display to develop your base fuel map. Using this portable display while driving and a computer to program your ECU you will be able to fully develop your base fuel map without the need for expensive and difficult to obtain dynamometer time. If you have access to a sophisticated dynamometer you can shorten your development time simply by using the on screen displays shown in the AUTOCAL program which tell you exactly how much fuel to add or subtract at any given point in the base map. Fuel calibration is a difficult process which cannot be completed on a dynamometer alone. Actual driving cycles are necessary to adjust your programming to provide accurate transition fueling. Whether you use our portable air/fuel ratio meter or take a ni-cad powered portable PC along for the ride you will have to drive the vehicle to perfect the fuel injection program. RSR calibrates specific systems but we cannot develop the programming for every possible application. Our software and support instrumentation will allow you to quickly perfect the RSR system on your particular vehicle.
ON-BOARD DIGITAL AIR/FUEL RATIO METER
This is the best investment I ever made Powered by The vehicle's 12 volt system this meter is directly connected to the Bosch Lambda oxygen sensor located in The exhaust system. The meter has a 10 L.E.D. display consisting of three green, four yellow, and three red lights. These lights represent a digitized instantaneous readout of air/fuel ratios ranging from 16~8:1 to 10.3:1. I can instantly 'see' My airifuel ratio and make adjustments based on this information. There is no need to look at The spark plugs or to guess if the motor is 'rich' or 'lean' at any one point to include transitional fueling. On closed loop RSR fuel injection systems the display will show oxygen sensing as well as all other functions such as accelerator pump fueling and high speed fuel cut-out on deceleration. Using this on-board meter I can quickly develop A base map.
FUEL INJECTION COMPONENTS
FUEL INJECTION FILTERS: Fuel injectors and injection fuel pumps should not be operated without filters designed specifically for fuel injection. Gas tanks and in-tank filters cannot be trusted to provide the filtration necessary to guarantee trouble-free long term operation of pumps and injectors. The fuel pump must be prefiltered to a 70 microns or less and the fuel injectors to an even finer degree (5 microns). Do not use any 'billet aluminum' style filters that use sintered bronze or paper elements as these are too restrictive and do not provide the filtration capacity necessary.
FUEL INJECTOR SIZING: To select a proper injector for your application you need to know the intended peak horsepower and of course the number of injectors in the system. We use the well agreed upon Brake Specific Fuel Consumption (BSFC) figure of .5 lb fuel/hp. hour for most engines. For example on a 3OOhp 8 injector RSR system: 3OOhp x .5 lb fuel/hp hr.: 150 lbs fuel/hr. 150 lbs fuel/8 injectors : 18.75 lb/hr injectors @ l00% duty cycle. A conservative correction factor would be to run the injectors at a 70% duty cycle as you should never hold the injectors wide open or 'static'. To calculate the injector size divide the calculated static figure of 18.75 lb/hr by .7. This gives you 26.76 lbs/hr or a 25 lb/hr injector. In this application your injectors would be using a 70% duty cycle to maintain a constant 300 hp. A simple formula is
Horsepower x .5 lb/hr. = lb/hr per
.7(# of injectors)----------injector

If you wish to correlate cc's per minute to lbs/hr. lO5cc per minute equals 10 lb/hr. Thus an injector that flows 315cc per minute flows 30 lb/hr.
The RSR Fuel Injection System is calibrated at 51 psi of fuel pressure at 0" vacuum. If you use A Adjustable Fuel Pressure Regulator you can calculate alternative injector delivery rates, stated in lbs/hr by using the following formula:
