The Triumph Rocket III Roadster incorporates a massive, liquid cooled, DOHC, 2.3L (2,300cc) in-line three-cylinder engine which is quite a sight. More remarkable is the whopping power output of 148 hp at 5,750 rpm and 163 ft-lbs at 2,750 rpm. The Triumph Rocket III transfers all the power to the rear wheel courtesy of a shaft drive. Stopping power up front comes courtesy of twin 320mm floating discs, Nissin four-piston fixed calipers and a single 316mm disc and two-piston Brembo caliper in the rear. ABS is standard.
