Introduction
The Triumph Rocket III Roadster is well known for its status of having the largest displacement engine of a production motorcycle. With a whopping 2,294cc or 140 cubic inch, 3-cylinder engine.
Development of the Triumph Rocket III Roadster began in 1998. It was intended to be a competitor to Harley Davidson Ultraglide and the Honda Goldwing. So initially the target engine displacement was 1,600cc.
However, in 2002 Yamaha launched it's 1,670cc Road Star Warrior. And, at the same time Honda launched it's 1,795cc VTX1800. Triumph decided to raise the bar. Squeezing in a 2.3 litre engine.
Released in 2004, the bike never quite managed to win over the loyal Harley and Goldwing riders. But as Motor Cycle News said, "The Triumph Rocket III is an incredible experience and bravo to Triumph for making it." They also went on to say that "Compared to a Harley, the Rocket III is a steal. It’s better braked, faster, handles better and it’s British."
The sheer force and presence of the Triumph Rocket III continues to deliver a simply stunning riding experience. An unmatched experience on two wheels.
