The Tuono V4R is the only naked powered by a narrow V (65°) 4 cylinder engine with unique characteristics. Extremely compact, as slim as a twin-cylinder and installed in an ultra-compact chassis, the 65° V4 engine is the epitome of Italian engineering ingenuity. The Tuono gives away very little to its RSV4 sibling in terms of pure performance, but in exchange offers a greater fluidity that make it more enjoyable and rewarding to ride on the road and when carrying a passenger.
Power 167.3 hp at 11,500 rpm
Torque 111.5 Nm at 9,500 rpm
Rev limiter 12,300 rpm in all gears
To achieve these results, a number of different modifications were made to the Aprilia V4 engine:
• New valve timing diagram.
• Fixed intake ducts now 20 mm longer.
• Crankshaft flywheel with increased inertia for improved smoothness and overall balance.
• Shortened gear ratios for the first three gears.
• Engine speed at maximum power reduced to 11,500 rpm on the Tuono V4R
