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 2.3 litre, three-cylinder engine is designed to be an arm-wrenching thrill to ride, yet easy and unintimidating too, despite its thunderous roar. Its sweet handling chassis, rigid frame and sophisticated suspension gives you the confidence to sweep through corners and change direction with an agility that belies this Roadsters size.

The Rocket III Roadster is a totally unique kind of motorcycle with the most unmistakable presence on two wheels. A true one-off it defies convention and category.

Unmistakable presence of the World’s largest capacity mass production motorcycle
2300cc inline three-cylinder engine delivers a staggering 221Nm of torque
Carefully refined handling characteristics deliver exceptional balance and chassis control with a low centre of gravity

 Engine
 

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!

The latest engine is unrestricted thereby delivering its full strength in the first three gears giving it almighty punch.

Configuration

The three big cylinders are arranged lengthways along the bike to keep it manageably narrow and align the crankshaft with the shaft final drive, but to tame the reaction of the massive torque, the crankshaft counter-rotates so the bike stays steady when the throttle’s blipped.

Shaft Drive

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.

Chassis Frame

We developed the big, tubular steel twin spine design to be strong and rigid enough to contain this powerhouse of a motor. But we focused on giving you an improbable level of agility too.

Suspension

We gave the front end sports-bike-style upside down forks 43mm in diameter so they’re strong enough to cope with all the forces a bike like this can deal out, yet with sophisticated internals so you get a plush, controlled ride.

Wheels and Tyres

The rear wheel diameter on the Rocket III is 16 inches to emphasise the fatness of the back tyre but to give you a more agile bike too.

Brakes

A bike like this needs a pair of vice-like, four-piston callipers. Gripping the 320mm discs and backed up by our advanced ABS system and a huge 316mm disc at the rear.

Handling

What our design and testing teams have managed to achieve is a massive bike with genuine handling prowess. Giving you low speed balance and beautifully neutral steering so when you’re faced with a twisty road you can be filled with anticipation and confidence.

Riding Position

It's your stance that really separates the ride on a Rocket III Roadster from the Rocket III Touring.

We put the Roadster footrests back to a mid position and the seat forward. Sitting you upright and active for better control. Spacious and comfortable enough to cover distances and cruising, especially with a seat this plush and generously sized.

And, despite the bike's width, it's still slender in the middle so your legs aren't splayed apart uncomfortably. The Rocket III Roadster might be larger than life, but it's still designed to fit.

Equipment and Technology
ABS

The advanced ABS brakes on the Rocket III Roaster are fitted as standard. This is a massive bike that comes with huge amounts of control.

Instruments and Computer

This is a premium flagship motorcycle so we equipped it accordingly.

All the instruments are all there for you, fuel gauge, gear indicator, dual trip and clock in addition to the basic functions. Then there’s the signature massive twin headlights making a powerful style statement and lighting up the road ahead at night for safer riding.
