Aprilia RXV4 (factory) - Ready to race

Aprilia RXV4

FROM APRILIA'S DOMINATION IN THE WORLD SUPERBIKE CHAMPIONSHIP, THE MOTORCYCLE THAT ALREADY SET NEW STANDARDS FOR THE SUPER SPORTS STREET BIKE GENRE: APRILIA RSV4 FACTORY APRC.

A SYMBOL OF THE “RACE READY” BIKE, RSV4 FACTORY APRC IS EVEN FASTER AND SAFER ON THE TRACK TODAY THANKS TO THE APRC DYNAMIC CONTROLS PACKAGE.

THREE INNOVATIVE SYSTEMS PATENTED BY APRILIA WHICH CONSTANTLY MONITOR THE DYNAMIC CONDITIONS OF THE BIKE AND OPERATE ON THE ENGINE CONTROL TO SUPPORT THE RIDER IN REACHING MAXIMUM RACING SPEED.

RSV4 factory is Created with the single-minded goal of being simply the best on the track and on the road, since its inception the Aprilia RSV4 has astonished the world with its looks, technology and performance.

IT is the first time to ever use a 65 degree V4 engine technology in a production moter bike.
and The multi-adjustable suspension, taken for granted on a motorcycle of this level, are combined with three chassis adjustments: headstock position and rake (through interchangeable bushings), rear end height, swingarm pin height and the engine position in the frame.
it is the only super with next generation ride controle system unlike any other bike out there. it got APRC APRILIA PERFORMANCE RIDE CONTROL system which is the most advanced ride control system on a motorbike till now.

APRC:

This is the most significant among the new features of the Aprilia RSV4 Factory APRC, a technology platform that is one step above any other systems available in the market, not yet available on all racing bikes. The transfer of know-how from racing to production has resulted in an electronic management system that is extremely sophisticated but also intuitive and very user friendly.

what APRC does is it uses an automotive inertial sensor platform with two gyrometers and two accelerometers allowing the ECU to recognise the dynamic conditions of the bike and adapt the engine management parameters accordingly. The rider can adjust any component of the APRC system independently at will.

ATC:

The ATC- Aprilia Traction Control undoubtedly is one of the greatest strengths of the APRC package. This is a fully innovative traction control system developed from an Aprilia patent, mainly focussed on helping the rider improve his lap times. Thanks to the inertial platform and the Ride By Wire pioneered by Aprilia, the ATC not only reduces torque when the rear wheel slips but lets the rider control tail sliding when exiting a bend, giving him a better feel for throttle control, depending on lean angle.
Aprilia ATC is quickly, easily activated from the instrument panel menu and offers 8 settings. When the ATC is enabled, the rider can change setting in an instant at any time using a joystick on the left handlebar to suit track, pavement or tyre conditions, without closing the throttle and keeping his hands on the handlebar, as in professional motorcycle racing. This way, the system can adjust to every single bend of any track so as to meet the specific requirements of any rider, including the most expert ones.
The other incredible achievement of Aprilia technology is the system's "learning capacity". Current traction control systems are designed and optimised for a single size and type of tyre. This limit frequently cancels the benefits of traction control. Aprilia Traction Control (ATC) has overcome this limit: a procedure activated by the rider enables the system to learn the tyre radius and final ratio adopted on the bike to obtain fine-tuned traction control.

AWC:

Exploiting the full power of modern superbikes down to the very last HP is every rider's dream. Aprilia's AWC (Aprilia Wheelie Control) has achieved extraordinary results. Thanks to the exclusive Aprilia patented Wheelie Detection System, the AWC is able to “tell” when a wheelie begins and ends and kicks in to smoothen wheel contact with the road. Smooth, soft wheelie management avoids harsh power cuts or pick-up, providing perfect acceleration control. Again, the AWC system is activated from the instrument panel and can be adjusted independently from other control systems choosing from three settings to better meet rider requirements.

ALC:

The perfect start is yet another racer's dream, because a good start frequently means you're half way towards a victory. When the lights go out, handling the huge power of modern superbikes is no easy task. Unless the bike handles it itself to offer its best starting performance. The ALC (Aprilia Launch Control) system ensures an instant start as the lights go out, applying full power to the road to assist the rider in this critical moment of the race. All the rider needs to do is give full throttle and release the clutch as he normally would and shift gears. The ALC has three settings that can be selected from the instrument panel menu, then it must be “armed” at standstill, by squeezing both traction control buttons on the left handlebar joystick at the same time.

AQS:

When you're after the utmost lap performance, you can't afford to waste even one thousandth of a second in an apparently simple operation like shifting. RSV4 Factory APRC is the first Aprilia bike that comes with the Aprilia Quick Shift as standard. Basically, the quick shift shortens spark advance for an instant and then gradually restores it, making for super-fast shifting with no need to close the throttle or use the clutch. The system works hand in hand with the new closer spaced gearbox to limit RPM drop during shifting for faster lap times. To optimise AQS performance, Aprilia engineers have fine-tuned power cut timing based on shifting RPM.

RSV4:

A combination of superior mechanical and electronic technologies can only lead to excellent rideability.RSV4 factory is for special riders who demand top sport riding performance.

Prestigious materials, an ultra-sophisticated suspension and the APRC system make the RSV4 Factory APRC quite simply the most advanced and highest performance sports bike on the track.

CHASSIS

The bike retains the unique chassis and swingarm solutions that make it the world's first “race ready” V4 superbike. In order to boost chassis performance and make it match the rider's tastes, or features of the track, Aprilia RSV4 Factory ensures a combination of adjustments that are pretty much infinite. The multi-adjustable suspension, taken for granted on a motorcycle of this level, are combined with three chassis adjustments: headstock position and rake (through interchangeable bushings), rear end height, swingarm pin height and the engine position in the frame.

Suspension

The Öhlins Racing upside-down fork has 43-mm diameter stanchions and is titanium nitride coated to minimise friction. The wheel travel is 120 mm. As on a racing bike, the fork allows millimetre-precise adjustment for hydraulic compression and rebound damping and spring preload.
The Öhlins Racing rear shock absorber was developed from experience learned directly on the track. It features a piggy back nitrogen canister (separate and mounted on the body of the unit) and adjustable spring preload, compression and rebound damping and length, allowing the height of the rear end of the bike to be altered to modify the set-up to suit different riding styles and tracks. Wheel travel is 130 mm.

Wheels and tyres
The effort to shed as much weight as possible and offer the best feeling led to implementation of new, ultra-light forged aluminium rims.An almost obsessive pursuit of top performance resulted in an exclusive, innovative dual blend tyre developed in collaboration with Racing Department, R&D and Pirelli. The racing sized 200/55 ZR17 tyre offers a better contact pattern in bends, shaving precious tenths of a second of lap time - a technology unique to this bike.

pros and cons:

when we are going to bye a race bike what we first look at is if the bike is cost affective or not.
there are many class leading bikes out there like Yamaha's R1 which is a very successful bike on track as well as road.when it comes to cost RSV4 is way to costly then R1. the R1 is 11 grand and RSV4 is 15 grand 4 grand much then a R1 .so its a down point when it comes to cost for RSV4.
when it comes to engine RSV4 got a cracking engine with really flat power band.the R1 engine is more refined and its throttle response is very well than RSV4 and it has very smooth power delivery.but RSV4 is quite strong at high range than a r1
RSV4 handling is bit better when compared to R1 but not that noticeable.

Aprilia and yamaha r1

noise is another major part of a super bike which gives that exiting feel to ride.when it comes to noise compression RSV4 is winner but R1 also sounds very good.

choosing between these bike is your choice because R1 is very smooth and is better on road and it is really cost effective.aprilia tho is a very race focused bike so it is better then an R1 on the track because it got most advanced ride control then R1and it takes advantage of fully adgestable chassis and suspension system which is very helpful on track.but on Road R1 is better choice

Conclusion

rxv4 rare

ok now here we are A real Super bike 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 APRC, the details say it all: no other "race ready" motorcycle has ever been built with such care and attention. The attention paid to its construction not only satisfies the desire for beauty but also the aims at achieving the goal:TO WIN. RSV4 is a full fledged race bike.
