The ultimate power cruiser.
The Triumph Rocket III has defined a unique niche in the clone-like performance cruiser market where it sits in a class of its own thanks to its striking looks, stunning performance and incredible specification. At 2294cc it's the world's largest capacity production motorcycle. But, despite the impressive capacity of this amazing machine, it was designed first and foremost to be ridden. A good turning circle, seamless fuel injection and a low center of gravity combine to make manoeuvring at low speed surprisingly easy.
Engine: The incredible 2.3 liter, 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.
Transmission: 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.
Brakes: The Rocket III's front brakes - twin four-piston calipers mated with 320mm floating discs – are built to sports bike specification and provide awesome stopping power. The rear brake, developed especially by Brembo, is a single twin piston caliper and 316mm disc.
Fueling: 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.
Suspension: The Rocket III's chassis is something quite special and centrers on a large tubular steel twin-spine frame, which houses the motor, while 43mm upside down forks and spring preload adjustable twin rear shocks, built specifically for the Rocket III, add control, composure and supple compliance.
