The RSV mille engine is a completely new unit, conceived and developed by Aprilia engineers.
Fuel is supplied by electronic injection with intake of air through a series of dynamic air intakes.
The ignition control system, also controlling injection, is integrated with the engine. The solution of out of phase connecting rod pins was discarded as it would have necessitated an excessively large timing case. This system uses an anti-vibration countershaft which, by rotating in the opposite direction to the drive shaft, balances the first order forces. Adoption of this technology results in an engine with excellent power, torque and output characteristics with extremely low vibrations. Dry sump lubrication Aprilia has made yet another innovation in this new engine.
