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.
