With the world’s biggest production motorcycle engine the latest Rocket III Roadster builds on the huge performance of the original Rocket III but now with even more torque.
The capacity of the Rocket III Roadster is huge, 2,294cc, and with a gut churning 221Nm at just 2,750rpm it has more torque at idle than most superbikes at full chat.

With a shaft drive that needs no maintenance outside the scheduled service intervals, you have a roadster that’s so reliable, durable and engaging that you could even go touring on it.
The three big cylinders are arranged length-ways along the bike. To tame the reaction of the massive torque, the crankshaft counter-rotates so the bike stays steady when the throttle’s blipped.
