The downsizing is also expected to reduce peak output by 3-5hp compared to the current engine used by Triumph Motorcycles. The existing 399cc, single-cylinder, liquid-cooled unit produces 40hp and 37.5Nm in most models, with the Triumph Thruxton 400 receiving a 2hp increase. This similar approach may be considered for the KTM 390 range and Bajaj Auto’s Dominar 400 and NS400Z, though no timeline has been announced. The Triumph Speed and Scrambler 400 is powered by a 398.15cc single-cylinder, liquid-cooled motor that puts out 40 hp and 37.5 Nm of torque. The engine is mated to a 6-speed gearbox. The Thruxton 400 too is powered by the same 398cc liquid-cooled single-cylinder engine from the Speed and Scrambler 400. But here, it’s been tuned to produce more power. It now delivers 42hp, up by 2hp with peak power coming in at 9,000rpm, which is 1,000rpm higher than the original. Torque stays the same at 37.5NmSource: CNBC TV18
