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 start 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 impressive specification 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!
Features
125cc 4-stroke engine with 5-speed gearbox
Driven by a 125cc 4-stroke engine, the TT-R125 delivers plenty of smooth power for spirited off-road riding. Being air-cooled, this punchy little engine requires relatively simple maintenance, and with a 5-speed gearbox and manual clutch, this model prepares the rider for the day when they move up to a more full-sized motorcycle.
Rugged long-travel front and rear suspension
Check out the compact steel frame and rugged suspension systems and you can see that this is a seriously capable off-road motorcycle. The sturdy front forks offer an impressive 180 mm of wheel travel, while the link-type rear suspension gives 168 mm of movement, allowing the TT-R125 to handle some seriously tough terrain.
Front disc brake and rear drum
To handle the TT-R125's punchy performance, the bike is equipped with an efficient 220mm diameter front disc brake that allows the rider to reduce speed with minimum effort. A 110mm drum brake delivers smooth stopping power at the rear end, and for good traction in the dirt the TT-R125 runs on a chunky, 90-section rear tyre.
Light and tough YZ-inspired Icon Blue bodywork
The sharp bodywork on the TT-R125 is inspired by our MXGP-winning YZ motocross bikes. Made from specially developed polypropylene that combines low weight with high strength, the fenders, tank panels and side panels are built to handle some tough treatment. Finished in Icon Blue, the TT-R125 has a genuine race bike image.
Large-diameter wheels
To complement the rugged chassis and long-travel suspension systems, the TT-R125 is equipped with a 19-inch front wheel and a 16-inch rear wheel. This large diameter gives greater ground clearance and enables the TT-R125 to handle uneven off-road surfaces better – for a more enjoyable ride.
Rider-friendly performance
The TT-R125 offers a combination of winning motocross styling, rider-friendly performance and a low seat height, making it ideally suited to both young and adult riders who want to gain valuable off-road experience. With a 5-speed gearbox, large-diameter wheels and YZ-type bodywork, the electric-start TT-R125 delivers a real 'big-bike' experience.
