New airbox and silencer for sharper power characteristics

The 2026 “New TF 250-X” announced by Triumph Motorcycles is a cutting-edge machine developed to win in motocross competitions. This update features a newly designed airbox and silencer that thoroughly pursues intake and exhaust efficiency. This improves intake efficiency and response while meeting the strict exhaust noise regulations of the FIM and AMA, enabling sharp acceleration that leaves rivals behind.
The ECU mapping has also been completely redesigned, making power delivery more direct across the entire range. The instantaneous power at the start and acceleration from the mid-range are truly race-spec. Furthermore, it is equipped with a new Exedy clutch with significantly increased torque capacity, improving clutch engagement accuracy and durability. This allows it to maintain tough performance even in the grueling heats of consecutive motocross races.
Thoroughly tuned chassis and suspension for sharp cornering performance

The chassis is based on a lightweight aluminum spine frame and is combined with a hydroformed swingarm to ensure optimal flex. This further improves cornering stability and traction performance. The KYB 48mm AOS coil fork and 3-way adjustable piggyback shock have been specially re-set, including the link mechanism, to further improve mid-range stroke control and chassis balance. This allows the machine to move exactly as the rider intends, even when banking at a high pace, and allows for active control of the front and rear load.
Furthermore, the design of the oil level window has been revised to improve maintainability, and the rear battery tray position has also been changed to facilitate quick maintenance at the race site. These improvements truly reflect feedback from actual races.
Cutting-edge electronic control and equipment: factory specs realized in production vehicles
The electronic control system has also undergone significant evolution. The Athena ECU precisely manages traction control and launch control, transmitting ideal driving force to the rear wheel according to the engine speed. The quick shifter allows clutchless acceleration from 2nd to 5th gear, and there is no loss of power even when shifting up instantly.
Furthermore, by using the optional MX Tune Pro Wi-Fi module, you can change fuel mapping, log real-time data, and even perform diagnostics from your smartphone. Triumph is the only company that puts the electronic tuning environment of a motocross factory into your hands.
The bike is equipped with Galfer wave discs and Brembo floating calipers, DirtStar rims with Pirelli MX32 wheels, a ProTaper carbon core handlebar, and ODI lock-on grips, making it a racer-quality bike in every respect.
Dedicated dealer network and retailer information
The new TF 250-X is scheduled to be released in Japan from July 2025, and will be sold exclusively at authorized motocross dealers nationwide. Specifically, it will be available at four dealerships: Triumph Tokyo Bay, Triumph Hamamatsu, Triumph Fukuoka, and Triumph Kagoshima.
