Aprilia also brought the Tuono V4 R supersports bike to the EICMA Show. The 2011 New Aprilia Tuono V4 R features a new exhaust system with bypass valve, which is 2 Kg lighter than the system used on the RSV4 R and is powered by a V4 65° engine framed by the brushed aluminum elements.
One special feature of the 2011 New Aprilia Tuono V4 R is the APRC (Aprilia Performance Ride Control) joystick, the second generation 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 2011 New Aprilia Tuono V4 R APRC package 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).
V4 162 HP engine, the most advanced chassis to attack any path, APRC electronic management to create a "customized" bike for every riding situation.
After creating the best superbike of the new millennium, Aprilia revolutionises the supersports naked segment with its astonishing new Tuono V4R.
A bike that goes beyond the wildest dreams of even the most hardcore enthusiasts - the rider who, given the chance, would use a race bike just to go for a coffee.
