Forum post about Aprilia RSV Mille 2001
The engine is a narrow-angle 60º V-twin, with four valves per cylinder. A pair of balance shafts reduce vibration from the motor, and a combination of gears and chain drive double overhead camshafts in each cylinder head. Twin spark plugs give fast and effcient combustion, and an advanced fuel-injection system uses large 51mm (2in) throttle bodies to help produce the 97k”(130bhp) peak power.
The narrow angle of the engine allows the aluminium twin-spar frame to be compact and stiff, for dynamic handling. It also made for shorter engine design than 90º V-twin, allowing a sporty, short wheelbase. High-set footpegs and theslim profile of the bike give excellent ground clearance, allowing the extreme cornering angles necessary for race success. The track-spec, fully adjustable suspension at both ends, gives smooth wheel response, while the steering geometry combines quick steering with good straight line stability. Early designs wore red-painted Brembo four-piston brake calipers, but later model reverted to standard gold-finished calipers. What ever colour they were, these calipers supplied class-leading performance.
The RSV Mille was immediately compared with Ducati’s 916, another distinctive Italian 1000cc V-twin sportsbike. While the RSV does not have the classic beauty of the red Ducati, its handling is equal to the older bike, and the RSV engine is more modern and stronger everywhere. Indeed, Ducati soon replaced the 916 with the 996, complete with a much more powerful 996cc engine.
The importance of the RSV to aprilia cannot be overstated. Its engine has proven to be strong, reliable unit, and the firm has been able to build a whole range of large capacity bikes around it, well repaying the care ant time taken during its development.
