THE POWER TO MOVE YOU
The new 765cc Street Triple motor is based on the last 675 Daytona motor. To create the 765, Triumph simply took the Daytona motor’s bore and stroke as far as the existing engine design would allow – to keep the engine compact, and to avoid the expense of redesigning it from the ground up. As a result, the 765’s wider bores make room for larger valves – but revs are kept sensible with a 12,650rpm rev limit. Peak power is a claimed 121bhp at 11,700rpm and peak torque 57ftlb at 10,800rpm.
In fact, we measured the Street Triple at 125.8bhp at 11,750rpm and 59ftlb at 9500rpm. It’s unusual to find an engine makes more power on a dyno than a manufacturer claims, so it’ll be interesting to see if other Street Triple RSS are the same. The lower spec R and S models have modified cam timing and fuelling and make a claimed 116 and 111bhp respectively.
The 1050cc Speed Triple motor has been around since 2005 and is one of the smoothest on the market. It’s claimed to deliver 138bhp at 9500rpm and 82ftlb at 7850rpm, but we measured it at 126.9bhp at 9250rpm and 77.7ftlb at 8000rpm, on the same day, same hour and on the same dyno as the Street Triple. Which means these bikes have just 1.1bhp between them. The bigger engine makes a lot more torque, but with the extra revs there’s nothing in it at the top-end. Which puts the 765cc Street Triple and 1050cc Speed Triple on a very similar footing from a performance point of view.
