Next to the RS4, Aprilia also brought the Tuono V4 R supersports bike to
the EICMA Show. The new bike features a new exhaust system with bypass
valve, which is two kilos 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 new 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.
