Featuring long-travel suspension, a front disc brake and tough motocross-style bodywork, the rugged TT-R125 is the ideal bike for youth and adult riders – who want an enjoyable and easy to maintain fun bike that can handle any terrain.
Fun for one, fun for all.
At the heart of this durable off roader there’s a compact air-cooled 125cc 4-stroke engine delivering plenty of smooth and controllable power. An electric starter makes it easy to get moving, and the 5-speed gearbox allows you to get maximum enjoyment from the TT-R125 – wherever you may go.
The exiting specification also includes long-travel front and rear suspension for smooth and confident handling – as well as a 220mm front disc brake, impact-resistant polypropylene bodywork and a 19-inch front wheel and 16-inch rear wheel with knobbly tyres. Let the fun begin!

Designed for older kids who may be graduating from the mid-sized TT-R110 – as well as for adults who want a light and easy to maintain fun bike – the TT-R125 is the most powerful bike in the TT-R line-up.
