Aprilia released 127 high-res pictures of the 2011 Tuono V4 R and V4 R APRC, which was revealed back at EICMA show last November. The V4 R is one of its kind with a V4 engine which delivers 167hp at 11,500rpm and 111.5Nm at 9,500rpm. The R version features new valve timing diagram, longer intake ducts, shortened gear ratios, and new crankshaft flywheel with increased inertia. The 999.6cc engine is coupled with a 6-speed direct-control cassette-type gearbox.

The V4 R APRC is the most complete version of the Tuono line-up, equipped as standard with a steering damper and the APRC second-generation vehicle dynamic control suite. 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.
In keeping with the Aprilia tradition of creating state of the art chassis architectures, the aluminium 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. The result is maximum torsional stiffness and flexional stiffness optimised for improved feedback. 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 maximise directional control and stability for a naked capable of over 270 Km/h – on the track, of course – 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 centre of gravity, for exceptionally neutral behaviour and truly catlike high speed stability.
The spirit of the RSV4 in a feline body
The new bike is available in two different configurations – Tuono V4 R and Tuono V4 R APRC – and in a choice of three colours: competition black, sunlit yellow and wing grey.
