2020 Triumph Rocket 3

Less weight, more power: All-new three-cylinder roadster lives up to its name.

Fifteen years after its debut, Triumph’s big-bore three-cylinder cruiser, the Rocket 3, has been completely redesigned. Engine capacity is up from 2,294cc to 2,458cc, further cementing the massive Brit bike’s title as the world’s largest-displacement production motorcycle. Triumph’s claimed 165 hp is impressive, but 163 pound-feet of torque is the true showstopper. With the hopped-up powerplant comes a new chassis—aluminum frame and fully adjustable Showa suspension; single-sided, shaft-drive-integrated swingarm—and more aggressive styling. Sport, Road, and Rain modes tailor power output, throttle response, traction control, and ABS.

Triumph lopped off nearly 90 pounds for a claimed dry weight of 642 for the Rocket 3 R and 648 for the Rocket 3 GT; the new frame weighs half of the outgoing steel unit. Never mind the relaxed steering geometry and lengthy wheelbase, handling far surpasses that of the previous-generation model. “Triumph constructed a motorcycle that was expected to be unhinged and bordering on unmanageable—or at least it should feel like it,” Senior Editor Justin Dawes wrote after riding both models. “Instead, it’s easy as pie to ride. The Rocket 3 is phenomenal in its ability to accelerate, turn, and stop.”
