The 2011 Aprilia RSV 4 R APRC. Now with the same electronics package as the more expensive RSV 4 Factory APRC, this bike features 8 stage adjustable traction control, wheelie control, launch control, and quick shifter package. If this isn’t not enough for some, Aprilia added a better motor lubrication system, lighten the exhaust by 2kg and revised first three gears for better acceleration.
For the price of $16,999 in the United States the 2011 Aprilia RSV4 R APRC will come with 200/55 x 17 dual-compound rear tire (same as on the Aprilia RSV4 Factory APRC!). And as an icing on the cake, there are lighter wheels, a fully-adjustable Sachs rear shock, better fuel consumption and new looks.
Aprilia Performance Ride Control (APRC) cheat sheet:
Aprilia Traction Control (ATC) – the most advanced traction control system on the market. It’s the only motorcycle TC system that can be adjusted on the move instantly without shutting the throttle and automatically adjusts to suit if you change your tyres. Features 8 level settings, so you can turn it down for track use or up for wet road riding on the go.
Aprilia Wheelie Control (AWC) – Identifies the start of wheelie and controls it to maximise acceleration whilst keeping the front end down. Features 3 settings.
Aprilia Launch Control (ALC) – Optimises acceleration from a standing start. For track/race use, with 3 settings.
Aprilia Quick Shift (AQS) — for ultra-fast clutchless up-shifting.
Review
We are living times for motorcycle technology, very special. On the one hand we live rescue of small displacements, Built on the bikes easy and basic techniques known and tested, sometimes to the limit of recycling, while at the other extreme we find technologies that evolve at the speed of light in search of ever greater performance.
And ‘there, in the segment of the race replica that come the most important new techniques, borrowed from the world of racing and coming, year after year, the bikes that we can buy in the dealership.
Aprilia, Which has always stood for innovative capacity and its technical expertise, introduces important new supercar on its top in 2011.
The RSV4 R, We tried on the track at Estoril now takes the name APRC which represents a significant technical difference compared to the 2010 version, as it means that even the “basic” model the package is installed Aprilia Performance Riding Control. The RSV4 R 2011 also brings with it the other improvements introduced since the RSV4 Factory APRC and then extended to V4 Tuono R.
Changes accordingly, the price rising to marketing € 18,000, While the rest of the budget, including color with black competition as opposed to white glam, remains unchanged.
As anticipated, the Aprilia has introduced the electronic package APRC at the end of 2010 when it launched the RSV 4 Factory Special Edition version of the already developed RSV 4 Factory performance.
The electronics package APRC (Aprilia Performance Ride Control) is, at present, the most advanced management system, dynamic driving available on the market.
It basically consists of four sub-systems that operate in a coordinated and synergistic: ATC, AWC, ALC and AQS using the signals received from an inertial platform, with two accelerometers and two girometri that allow the unit to reconstruct the dynamic conditions of motion and respond accordingly to the engine control. The pilot can adjust freely and independently of each system component APRC.
The system is obviously the most important dell’APRC ATC Aprilia Traction Control. This is an innovative traction control system, developed with patented Aprilia, which has as main goal to help the pilot to improve his lap time. Thanks to the use of the inertial platform and ride-by-wire, ATC operates on the control of torque from the engine according to several steps, and allows the rider to control the drift out of corners, increasing its sensitivity on the throttle, depending on the angle of inclination of the bike.
Traction control is adjustable on 8 levels, simply by pressing the joystick on the left handlebar to adjust the level of traction control to the track conditions, tires or asphalt.
The AWC is another of the important features dell’APRC, which is directly derived from competitions. In race, in fact, a surge can be choreographed, but it wastes time on tour and has imported the Aprilia Wheel Control on motorcycles. wheelie detection system is able to “understand” when it starts and ends sharply and acts accordingly to gently pull the front wheel on the ground. Dell’impennata management is continuous and “soft”, there are no cuts or sharp shooting of violent power, but only proper throttle control. The AWC is activated from the dashboard and can be adjusted independently from other controls three levels of intervention, Thus favoring the needs of the pilot.
He could miss the Launch Control on a motorcycle last generation? Aprilia think not, and here also the RSV4 R is equipped. The ALC is able to put all available power to the ground without losing a single engine newton meters of torque under acceleration. The Aprilia Launch Control allows the rider only the task of open up the gas, As would normally release the clutch and change gears. The system adjusts to three levels using the menu on the dashboard and then “Weapon” stop-motion, squeezing together the two joystick buttons on the left handlebar that allows the pilot to operate the traction control.
Last but not least the Aprilia Quick Shift, the shifting device that allows you to get quick report without closing the throttle without the clutch. It is a well-known accessory for many years, who is appearing on the stock bike for a few seasons.
The quick change feature of the Aprilia is to work in synergy with other electronic systems and to have response times that vary depending on engine speed and gear.
We tried the new version of the Aprilia RSV4 R on the track of Adria. Although the track Veneto is not ideal to assess properly the dynamics of a motorcycle, Because of its size and design that provides only for the narrow hairpin bends, is useful just to test the new APRC.
Adria, in fact, you find yourself having to fully open the throttle out of corners, as they are all very slow and you travel on almost all gas closed, and you can evaluate the action of Traction Control.
The RSV4 R, for its part, keeps well the dynamic characteristics of the sister factory, a little watered down ‘by suspensions of more economical extraction original equipment tires and less sporty.
The bike is confirmed very sincere and well trimmed, the front end is inserted into the fold by taking the rope with the decision, but the center curve is not able to follow the same lines as the sister factory, expanding a little ‘too if you enter the trajectory determined . Out of the corners the shock absorber does what it can to keep the Michelin Power 2CT One in contact with the asphalt, but the wheel is not up to the Factory.
The suspension under braking bumps well raking asphalt Venetian, but they are still quite soft and the bike jumps a little ‘when you force a lot under braking. Considering that the load transfer is remarkable, and we shot with the rear higher than the standard, the brakes must be used with care because behind the brake trigger flag-wavers of exaggerating the rear.
But we all’APRC. The system Made in Aprilia is really effective: already at the center curve, you can take the gas to hand without the risk that slides back and focus on the output curve to achieve better acceleration on the straight below.
A medium caliber rider feels the inclusion of the system when the bike is in the middle of the fold and gives background gas, through a gentle reduction in power output that does not break the bike as it would sharply cut the injection.
Output from the tight hairpins of Adria, which is often used in first gear, is strongly supportive of the Control dell’impennata, Which allows you to touch the tarmac without losing time to do the blowhards …
Quick Shift also gives praise, which, together with the new close-ratio gearbox with, can earn significant acceleration milliseconds. We repeat, is not a novelty, but on the track is an invaluable aid to driving.
In conclusion, the new RSV4 R APRC confirmed to be a super-class, refined technique with a budget that has as unique in the suspension Sachs a little ‘too compliant for a bike that still is to a figure which itself is above the four-cylinder rivals.
In other words … you have got to put in budget spending of 18,000 euros for a supercar, it might be worth making a few more installments, just get the Factory version.
