The Street Twin was Triumph's accessible entry to the Bonneville range, introduced for 2016 with a new 900 cc high-torque 270 degree twin in a 55 hp tune. It brought a fresh frame, ABS, ride-by-wire, switchable traction control and a low seat, and served as a base for the Scrambler, Brat Tracker and Urban accessory kits.
