Triumph, the renowned British motorcycle manufacturer, is poised for the global premiere of four new motorcycle models on October 6th, 2026, with the highly anticipated Bonneville 400 confirmed for an Indian debut.

The India-spec Bonneville 400 will likely be powered by a new 349cc single-cylinder liquid-cooled engine, similar to that found in the Speed 400 and Scrambler models, producing a maximum power of 36.5 bhp and peak torque of 32 Nm. Spy images have revealed a production-ready model featuring a new chassis and swingarm, with a redesigned rear subframe to accommodate a flat, bench-type seat and an elongated rear profile.
