A cafe-racer version of Triumph's 400 single platform, with clip-on bars, rear-set pegs, bar-end mirrors and a round LED headlight. It has the most powerful tune of the 398 cc engine so far, with ride-by-wire, switchable traction control and a torque-assist clutch. A small, approachable successor to the Thruxton name.
