How Much Power Does the 2020 Triumph Street Twin Make?

Horsepower and torque figures on Triumph’s approachable modern classic

There’s something so attractive about the 2020 Triumph Street Twin’s simplicity. Sure, there are a number of killer motorcycles available that rule the spec sheets or ultra-focused areas of performance. But then there’s the Street Twin—an elementary modern classic motorcycle with a seriously engaging riding experience.

Highlighting the Street Twin’s ride is the smooth nature of its liquid-cooled, eight-valve, SOHC, 899cc parallel-twin engine with its 270-degree firing order. It was recently updated for the 2019 model year, receiving a lighter-weight crankshaft and redesigned balance shafts as well as a magnesium camshaft cover and lighter clutch cover. The real-world result is an engine that “delivers steady, usable power across its five gears with plenty of torque in the low midrange and a long-stretching fifth,” as Serena Bleeker said in her first ride review.

We ran the Street Twin on our in-house dyno to get the hard numbers. The Triumph produced 60.06 hp at 6,880 rpm and 55.60 pound-feet of torque at 3,730 rpm. What’s most remarkable is just how agreeable the curves are. That is, how incredibly linear the power curve is and how broad and flat the torque is, which offers the flexibility in delivery that Bleeker praised. There’s more than 50 pound-feet of torque available between roughly 2,750 rpm and 6,000 rpm. All in all, a sensible, friendly ride with classic good looks and wonderfully usable power.
