Triumph Motorcycles has officially launched the new TF 250-X, revealing a class-leading power-to-weight ratio and the most complete specification package ever to launch into the ultra-competitive 250cc motocross market.

Developed entirely by Triumph in close collaboration with racing champions including Ricky Carmichael and Iván Cervantes, the new four-stroke competition model is an all-new ground-up design. The performance racing powertrain and unique aluminum chassis are ultra-compact and super light, with all the best components on the market, already fitted out of the crate. With a focused and aggressive style, the TF 250-X is slim, yet bold. It will be instantly recognizable on the track, with its minimal and lightweight presence and distinctive Triumph Racing Yellow and Black graphics scheme. A network of Triumph dealers will offer sales, service, parts, and a new dedicated range of apparel. The network will be backed by a mobile-optimized 24/7 online parts supply system, so owners can order for express delivery, straight from the track.

Performance Racing Powertrain Triumph has developed an all-new performance racing powertrain. The new competition four stroke single is ultra-compact and super-light, with a forged aluminum piston and titanium valves. The engine also has diamond-like carbon low-friction coatings, lightweight magnesium covers, and an Exedy Belleville clutch. Advanced engine management and tunability is complemented by the optional accessory MX Tune Pro app, enabling riders to use real-time user-selectable mapping, a real-time engine sensor dashboard, and live diagnostic functionality, through a controlled and programmable engine management system.

Racing Pedigree Triumph’s globally renowned engineering teams bring expertise in precision engineering, innovation, and award-winning quality.

From factory World Supersport racing to multiple Supersport wins at the Isle of Man TT and the Daytona 200, the teams are focused on success. The team has been supported by some of the biggest names in motocross, including the greatest MX rider of all time, Ricky Carmichael. He has worked with the Triumph chassis and engine teams across the journey of scoping, prototyping, testing, and development.
