Aprilia Tuono V4R

The Aprilia Tuono V4R is an evil looking high-performance sports bike which is basically the unfaired version of the Aprilia RSV4 R.




The Aprilia Tuono V4R boasts power never before installed on a factory naked bike, obtained by reconfiguring the RSV4 Factory APRC SE four V cylinder. The Tuono V4R uses features from the Special Edition including the new 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. Differences from its race track sibling are closer spacing between the first three gear ratios, and a maximum torque output of 110 Nm on tap 1,000 rpm lower. The Aprilia Tuono V4R features the same tail fairing, saddle, tank and side panels as Aprilia's WSBK racing machine.



The Tuono V4R uses the second generation version of Aprilia's APRC (Aprilia Performance Ride Control) joystick - an electronic dynamics control package developed by Aprilia to get as close as possible to the physical limits of riding. APRC is based on an automotive inertia sensor platform, with two gyrometers and two accelerometers allowing the 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 in all conditions.



The APRC package of the Tuono V4R includes ATC traction control (Aprilia Traction Control), with eight selectable levels, which controls sliding when accelerating out of a curve in relation to bank angle and throttle aperture, AWC (Aprilia Wheelie Control), which helps the rider control extreme wheelying by gradually bringing the front wheel back to the ground, and AQS (Aprilia Quick Shift), which 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).



The Aprilia Tuono V4R also features a range of top-spec chassis components, including a Brembo brake system with radial callipers and 320 mm floating discs at the front (220 mm at the rear), aluminium wheels with an all-new design weighing 2 Kg less than those on the RSV4R, Sachs upside down front fork with 43 mm stanchions coated with titanium nitride for reduced friction, and Sachs shock absorber with separate piggy back nitrogen canister featuring adjustable spring preload, compression and rebound damping and length, to modify the setup of the bike to suit different riding styles or for when carrying a pillion.
