Triumph Speed T4 vs Speed 400: Engine & Performance

Both motorcycles are powered by the same 398cc, liquid-cooled, single-cylinder engine. However, peak outputs are not the same. The Speed 400 delivers 39.5 bhp at 8,000 rpm and 37.5 Nm of torque at 6,500 rpm, while the Speed T4 is tuned to offer 30.6 bhp at 7,000 rpm and 36 Nm of torque at 5,000 rpm.
