The official spiel from Aprilia:
The Tuono gives away very little to its RSV4 sibling in terms of pure performance (167bhp @ 11,500rpm) but a host of engine tweaks make it more flexible for the road.
Changes include new valve timing, 20mm longer fixed intake ducts, crankshaft flywheel with increased inertia for improved smoothness and overall balance and shortened gear ratios for the first three gears. Plus the Tuono V4 R features latest generation Ride by Wire throttle control with three rider-selectable maps (Track, Sport and Road).
The RSV4 frame has also been modified specifically for use in the Tuono V4 R. This led to changes in chassis geometry, including modifying the trail and lowering the engine in the frame to lower the centre of gravity, for exceptional high speed stability.
The Tuono V4 R comes equipped with some of the best components on the market: Brembo brakes with radial calipers and 320mm floating discs at the front (220mm at the rear), aluminium wheels with an all-new three spoke design (2kg less than the five spoke version), fully-adjustable Sachs USD 43mm front forks and a Sachs shock absorber with a separate piggy back nitrogen canister (adjustable for spring preload, compression, rebound damping and length).
The Tuono V4 R is available with or without class-leading Aprilia Performance Ride Control (APRC) technology.
What is APRC? - Aprilia Performance Ride Control is an engine torque control system that helps improve performance and enhance safety for the rider. It includes:
• Aprilia Traction Control (ATC) – the most advanced traction control system on the market. It’s the only motorcycle TC system that can be adjusted on the move instantly without shutting the throttle and automatically adjusts to suit if you change your tyres. Features 8 level settings, so you can turn it down for track use or up for wet road riding on the go.
• Aprilia Wheelie Control (AWC) – Identifies the start of wheelie and controls it to maximise acceleration whilst keeping the front end down. Features 3 settings.
• Aprilia Launch Control (ALC) – Optimises acceleration from a standing start. For track/race use, with 3 settings.
• Aprilia Quick Shift (AQS) - for ultra-fast clutchless up-shifting.
The Tuono V4 R is £10,628 (OTR) while the Tuono V4 R APRC version is £11,628 (OTR).
