The Triumph Bonneville Street Twin
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 peak torque of 80Nm at 3200 rpm, which is 18% more than the previous model – 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 black engine cases and a high level of detailing. Incorporating contemporary engine components alongside signature features from the iconic Bonneville engine to enhance that authentic Bonneville silhouette.
The 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 –36% better than the previous generation Bonneville.
Dynamic Handling
The Street Twin’s fun, engaging and easy-going riding experience comes courtesy of an all-new chassis and suspension – designed to bring Triumph’s signature ride dynamic of neutrality and agility, and deliver refined and intuitive handling. Combining a user-friendly low seat, more substantial seat foam, greater suspension travel, a more natural riding position, slim waist profile and fantastic ‘stand-over’ ergonomics, the Street Twin is the most accessible Bonneville.
