New 900cc ‘high torque’ engine

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
