125 cc 4-stroke engine with 5-speed gearbox

Driven by a 125 cc 4-stroke engine, the TT-R125LW/E models deliver plenty of smooth power for spirited off-road riding. Being air-cooled, this punchy little engine is relatively simple to maintain, and with a 5-speed gearbox and manual clutch, both models prepare the rider for the day when they move up to a full-sized motorcycle.

Disc front brake and rear drum

To handle the TT-R125LW/E’s perky performance, the bike has an efficient 220 mm diameter front disc brake that allows the rider to reduce speed with minimum effort. A 110 mm drum brake delivers smooth stopping power at the rear end, and for good traction the TT-R125LW/E runs on a chunky, 90-section rear tyre.

Light and tough YZ-inspired racing-blue bodywork

The stunning bodywork on the TT-R125LW/E was inspired by our MXGP-winning YZ 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 racing blue, the TT-R125LW/E has a genuine race bike image.

To complement the rugged chassis and long-travel suspension systems, the TT-R125LW/E models are equipped with a 483 mm (19-inch) diameter front wheel and a 406 mm (16-inch) diameter rear wheel. Their large diameter gives greater ground clearance, and enables the TT-R125LW/E to handle uneven off-road surfaces for a more enjoyable ride.
