Trumph Street Twin Engine

New 900cc ‘high torque’ engine 

The unique character of the Street twin comes to life through the all-new 900cc ‘high torque’ 8 valve, parallel twin Bonneville engine. 

As the name suggests, it delivers a massive peak torque figure of 80Nm at a low 3200 rpm, which is an amazing 18% more than the previous model, delivered where you want it - low down and across the whole rev range. 

Benefitting from the pinpoint accuracy and instant throttle response of Triumph’s next generation ride-by-wire fuel-injection and engine management system, the Bonneville Street Twin is engineered with a charismatic 270° firing interval for an immaculately smooth, linear power delivery through the smooth six-speed gearbox.

The look of the new 900cc engine has also been beautifully crafted, with stylish black engine cases and a very high level of detailing. Incorporating contemporary engine components alongside signature features from the iconic Bonneville engine to enhance that authentic Bonneville silhouette.

The all-new upswept brushed stainless steel exhaust system of the Street Twin has been developed and tuned carefully to look great and deliver the unmistakable sound of a genuine British twin, with a rich, fruity note to match its lively character, tuned to a level you can feel as well as hear.

Significantly advanced fuel economy

Behind the new 900 engine’s stylish exterior sits a cutting-edge liquid cooling system, carefully integrated to minimise its visual impact whilst achieving cleaner emissions and enhancing fuel efficiency – an amazing 36% better than the previous generation Bonneville.
