The supersport naked segment has been astonished by the new 2011 Aprilia Tuono V4 R. The V4 65-degree engine sits in the brushed aluminum elements of the dual beam frame and is dressed only with the bare motorcycle necessities.
With an incredible 162 hp, the Tuono V4 R boasts power never before installed on a naked, obtained by reconfiguring the RSV4 Factory APRC SE four V cylinder engine.
The V4R inherits 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 three first gear ratios, with a maximum torque of 110 Nm on tap 1000 rpm lower.
Staying in the saddle and gripping the biconical handlebar, the motorcycle rider comes into contact with the APRC (Aprilia Performance Ride Control) joystick, the second generation electronic dynamics control package developed by Aprilia.
APRC is based on an automotive inertia sensor platform, with two gyro-meters 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 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.
The AWC (Aprilia Wheelie Control) helps the rider control extreme wheelies by gradually bringing the front wheel back to the ground, and AQS (Aprilia Quick Shift), which allows instantaneous up-shifts without closing the throttle or using the clutch.
Completing the suite of four functions is the most exhilarating of all: ALC (Aprilia Launch Control).
