2012 Aprilia Tuono V4 R APRC

Brakes and Wheels

• A state-of-the art Brembo brake system with radial calipers and 320 mm floating discs at the front and 220 mm at the rear. The three spoke aluminum wheels weigh 4.4 pounds less than the five spoke version.

Chassis

• In keeping with the Aprilia tradition of creating state of the art chassis architectures, the aluminum frame of the Tuono V4 R exploits the strength and flexibility of cast and pressed elements in a structure that sets new benchmarks in terms of balance and dynamic efficiency.
• Unlike the previous generation twin cylinder Tuono 1000R, the frame developed for the Tuono V4 R has been completely revised with respect to the unit used in the RSV4 to maximize directional control and stability while maintaining the legendary safety and impeccable precision typical of Aprilia frames. This in turn led to new solutions in terms of chassis geometry, such as modifying the trail and lowering the engine in the frame to lower the center of gravity, for exceptionally neutral behavior and truly catlike high speed stability.
• This means that the Aprilia Tuono is not just a bike with devastating performance, but one whose greatest strength is precisely the incredible ease with which any rider can access its full potential. The swingarm also uses the same constructional technology as the frame and offers the same perfect balance between flexional and torsional stiffness to contribute to the extraordinary responsiveness of the Tuono V4 R.
• The unique construction technology of the frame and swingarm allows them both to proudly flaunt the naturally gleaming color of brushed aluminum, yet another feature that is increasingly rare in production bikes that contributes to pure racing look of the Tuono V4.
• The Tuono V4 comes equipped with the best components available on the market.

Suspension

• A fully adjustable Sachs upside down front fork with 43 mm stanchions provides incredible feel no matter the riding situation. While a Sachs rear monoshock with separate piggyback nitrogen canister features adjustable spring preload, compression and rebound damping and length. You can modify the setup of the bike to suit different riding styles, roads and loads - including a passenger.

The Aprilia APRC Electronics Package

• APRC is based on an automotive inertia sensor platform, with two gyrometers and two accelerometers allowing the engine ECU to determine the dynamic state of the motorcycle and control engine torque accordingly to help the rider exploit the full performance potential of the bike.
• The APRC electronics package on the Tuono V4 includes:
• ATC (Aprilia Traction Control): With eight different traction control settings for in relation to turn angle and throttle aperture. The system has been tweaked to make the more conservative settings even more suitable for road use, while leaving the racing spirit of the less restrictive levels intact.
• AWC (Aprilia Wheelie Control): Helps the rider maintain control by gradually bringing the front wheel back to the ground. AWC has been appropriately adapted for the different weight distribution of the Tuono V4.
• AQS (Aprilia Quick Shift): Allows instantaneous upshifts without closing the throttle or using the clutch. Completing the suite of four functions is the most exhilarating of all: ALC (Aprilia Launch Control).
• ALC (Aprilia Launch Control): Simultaneously pressing both buttons on the joystick on the left hand handlebar arms the system, as confirmed by the specific message on the display. From this moment on, all 167 horsepower of the beast from Noale are ready to slingshot the Tuono V4 like a missile as soon as the rider releases the clutch, unleashing the astonishing power onto the tarmac through every available square millimeter of the 190/55 rear tire. And tire size does not matter to APRC, as with its calibrating function, it is the only system of its kind on the market capable of self-adapting to tire size.

The Engine

• The Tuono V4 is the only naked powered by the world championship-winning 65 degree V4 cylinder engine with unique characteristics. Extremely compact, as slim as a twin-cylinder and installed in an ultra-compact chassis, the 65 degree V4 engine is the epitome of Italian engineering ingenuity. The Tuono gives away very little to its RSV4 sibling in terms of pure performance, but in exchange offers a greater fluidity that make it more enjoyable and rewarding to ride on the road and when carrying a passenger.
• Power: 167.3 hp at 11,500 rpm
• Torque: 82 Ft. lbs at 9,500 rpm
• Rev Limiter: 12,300 rpm in all gears
• To achieve these results, a number of different modifications were made to the Aprilia V4 engine:
• New valve timing diagram
• Fixed intake ducts now 20 mm longer
• Crankshaft flywheel with increased inertia for improved smoothness and overall balance
• Shortened gear ratios for the first three gears
• Engine speed at maximum power reduced to 11,500 rpm on the Tuono V4
• The Aprilia 65° V4 engine specifications in short:
• Engine Capacity: 999.6 cc
• Architecture: 65 degree V4
• Crankcase: Monobloc with integrated crankcase liners
• Timing System: 4 valves per cylinder operated directly by a camshaft driven by a mixed chain/gear system (lateral timing chain and central gear train)
• Fuel System: Electronic injection with a single injector per cylinder and integrated independent Ride by Wire system for each bank. Three maps selectable from the handlebar (Track, Sport and Road)
• Anti-vibration countershaft
• Compression Ratio: 13:1
• Gearbox: 6-speed direct-control cassette type gearbox
• Clutch: Multi-plate wet clutch with mechanical slipper system
• Electronic Management: Magneti Marelli control unit managing ignition, injection and Ride by Wire system
• The narrow V architecture translates into an engine that is incredibly compact in length, offering advantages in terms of mass centralization and making it possible to define a chassis architecture center of gravity that is both very low and almost perfectly centralized in the engine and vehicle for neutral, intuitive behavior and maximum responsiveness on the road.
• The innovative valve timing system (with the chain camshaft driving only the intake camshaft, which in turn drives the exhaust camshaft via a single gear) has allowed the use of just 250 mm at the rear of the engine), especially in the area beneath the frame spars, which are thus much narrower than would otherwise be possible.
• The electronic management system is another example of the 65 degree V4 engine's technological supremacy. Full Ride by Wire technology eliminates any direct connection between the throttle grip and the throttle valves, which are entirely controlled by a latest generation Marelli control unit that also controls the ignition and the 4 injectors.
• Each bank has a dedicated servo unit actuating its own two throttle bodies. This means that the aperture of the throttle valves and, as a consequence, the quantity of fuel injected can be controlled independently. Aprilia has refined power delivery control.
• This technology, adapted appropriately for the prevalently road based usage of the Tuono V4, offers immediately tangible benefits to the rider, with triple mapping (adjusting power delivery and maximum power) selectable directly from the handlebar allowing the character of the bike to be modified to suit the rider's personal riding style or the track conditions at any time.
• T - Track: All 167.3 hp of power available at the slightest twist of the throttle.
• S - Sport: Smooth delivery, maximum power. Torque limited in all gears for fun yet less demanding riding.
• R - Road: Smooth delivery and power attenuated by 25 percent across the rev range. Greater usability in all conditions. Ideal for the city or wet road conditions.
• The transmission has also been designed to the meet most advanced criteria to offer the maximum performance possible. To underscore the racing soul of the 65 degree V4 engine, it is mated to a cassette gearbox with a wet sump lubrication system (with oil in the crankcase). The wet clutch features a mechanical slipper system for optimized engine braking torque control and stability under hard braking.

The Motorcycle

• With its 65 degree V4 engine brazenly flaunted and framed by the brushed aluminum twin spar frame, the Tuono V4 is a naked clad only with the bare minimum necessary to let you saddle up and teach it to respond to your will. Adding yet another touch of aggressiveness is the aerodynamic top fairing tipped with two polyelliptical headlights and LED indicators at the sharp end, which gives the bike the unequivocally mean, daunting stare that you'd expect from a machine with an incredible 167.3 horsepower.
• Tuono V4 boasts more power than ever seen before in a naked, achieved by reconfiguring the V4 engine of the RSV4 to make it better suited to street use. The features inherited by the Tuono V4 from the RSV4 include the exhaust system with bypass valve, which is two kilos lighter than the system used on the RSV4 R, and latest generation Ride by Wire throttle control with three rider-selectable maps (Track, Sport and Road).
• The first three gear ratios are now shorter, while the maximum torque (82 ft. lbs.) is on tap at 9,500 rpm: characteristics that make the Tuono V4 a wild beast at low and mid-engine speeds, with the ability to unleash a devastating hurricane of power at higher engine speeds.
• The Tuono V4 maintains a clear lineage with the SBK world champion, RSV4, in the proportions of the tail fairing, saddle, tank and side panels, and is one of the best examples of Italian motorcycle design from the past decade for its perfect balance between formal beauty and function.
• The rider benefits from a riding position tailored to create a symbiotic relationship between the body and the bike, for unparalleled feedback through the three points of contact - the saddle, footpegs and handlebars. On the Tuono V4 however, the rider sits with less weight on the arms, making the bike less strenuous to ride and extraordinarily nimble and controllable on the road.

Tires

• The choice of dual-compound tires is new, with three different sizes approved for the rear wheel: the 190/55 tire fitted as standard may be replaced with a 200/55 or a 190/50 tire to explore the full performance potential of the bike.
