Aprilia RSV4 Factory APRC Special Edition: Along with usual improvements, electronics are one-way route to better lap times.
Derived from Aprilia's press release, except from the paragraph comments.
State of art technology
This new technology is brought together in the APRC (Aprilia Performance Ride Control) package, basically the state of the art in dynamic performance control, a multi-patented system that makes Superbike winning technology available to professional racing riders and hobby riders alike. All this comes in an easy to use, intuitive package.
Aprilia RSV4 Factory APRC SE's improvements are not limited to the electronic management system. The 65° V4 engine offers improved lubrication and closer spaced gears for better acceleration. The new, lighter exhaust features an advanced butterfly valve management system to suit the Ride By Wire mapping for improved breathing and efficiency throughout the RPM range.
In addition, the Aprilia RSV4 Factory APRC SE is the first super sport bike sporting the homologated new-generation extra performance dual blend 200/55 tyres developed in collaboration with Pirelli based on the expertise gathered on World Superbike racing circuits.
All new features of the Factory Special Edition The new features introduced in the Aprilia RSV4 Factory APRC SE in detail:
-APRC Aprilia Performance Ride Control, the electronic management package including:
- ATC: Aprilia Traction Control automatically adjusts to different types of tyres, with 8 settings conveniently selectable while racing from a joystick on the left handlebar without turning down the throttle;
- AWC: Aprilia Wheelie Control with three settings;
- ALC: Aprilia Launch Control, for use on the track only, with 3 settings;
- AQS: Aprilia Quick Shift, for ultra-fast shifting without closing the throttle or using the clutch.
-Dual display mode for instrument panel display: ROAD and RACE;
-New exhaust is lighter and offers improved performance;
-Optimised gear ratios for the utmost track performance;
-Improved engine lubrication;
-New, exclusive 200/55 dual blend rear tyre.
The APRC package 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 traction control system of the future
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: stability at top acceleration
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 avoid 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 best holeshot
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: record-breaking shifting
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 SE 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.
Select valuable materials, ultra-sophisticated suspension, APRC system, and a dedicated livery make the RSV4 Factory APRC Special Edition the most cutting-edge sport bike with unsurpassed track performance.
RSV4 Factory APRC Special Edition highlights:
• APRC fitted as standard
• Fuel system with variable length intake ducts
• Advanced exhaust butterfly valve management
• 3-point adjustable chassis
• Öhlins fully adjustable front fork
• Öhlins fully adjustable shock absorber
• Öhlins adjustable steering damper
• Wheel rims in forged aluminium
• Carbon parts

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 suspensions, 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 - introducing a new capability exclusive to this bike - the engine position in the frame.
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.

Comments: The electronics era has come. Changes to be seen will be vast, superbikes will be a lot easier motorcycles to ride fast in the future.
ApriliaĒs aim isnĒt absolute horsepower numbers, just drivability.
ABS would help on low friction track riding or riding on the road. Consequently there are many electronic systems controlling the engine performance, none for the brakes, even as optional.
