Features of The Motorcycles

The incredible 2.3 litre, in-line, water cooled, triple cylinder engine means that even two-up the Rocket III accelerates incredibly hard without obvious effort. But despite its size, the engine is incredibly smooth as the balance, input and rear drive shaft contra-rotate against the crankshaft, which makes for minimal torque reaction.

Shaft drive is ideally suited to dealing with such a strong production engine and gives the added benefit of being highly durable and virtually maintenance free.

Twin butterfly valves for each throttle body are used to give precise control over the engine and this set-up allows the ECU to vary the mixture flow and ignition map dependent on gear selected and road speed. The torque curve is thus tailored specifically for each gear ratio. And the result is impressive – over 90% of the engine’s prodigious torque output is available at just 2000rpm, giving incredible levels of flexibility and making the five-speed gearbox almost redundant.
