Engineered to meet the new FIM and AMA race sound regulations, the all-new airbox and silencer have been designed to deliver both performance and noise requirements, while maintaining Triumph’s signature engine note. Combined with the new engine calibration, the TF 250-X will deliver a superior race-day performance.

The updated ECU mapping enhances power delivery and throttle response across the entire RPM range, enabling quicker launches and sharper corner exits, while the new high-performance Exedy clutch delivers more direct engagement, enhanced durability under extreme conditions, and significantly increased torque capacity. Updated suspension tuning also provides improved mid-stroke control, better chassis balance, and enhanced cornering stability. Ensuring better reliability and easier servicing, the layout for the battery tray has also been refined to improve accessibility, and the Oil Level Sight Glass has been redesigned to further improve clarity and accuracy.

To complete the 2026 updates, there is a brand-new graphics scheme for 2026, with striking in-mold decals in eye-catching Triumph Performance Yellow, which adds to the focused, aggressive style of the TF 250-X, ensuring a stand-out presence on the track. These updates build on the TF 250-X’s successful 2024 debut, developed in close collaboration with motocross legend Ricky Carmichael and World Enduro champion Iván

Cervantes. The TF 250-X set a new benchmark in the 250cc category with its class-leading power-to-weight ratio, factory-level KYB suspension, and advanced rider-focused electronics.

ENGINEERED TO DOMINATE

The high-performance four-stroke single-cylinder engine delivers 47.3 HP (48 PS) peak power at 13,500 rpm, which, paired with a unique ultra compact and super-light aluminum chassis, gives the TF 250-X the all-important class-leading power-to-weight ratio. Triumph’s performance racing powertrain has earned its stripes on the track. With a forged aluminum König piston and Del West titanium valves, the engine also has diamond-like carbon low-friction coatings and lightweight magnesium covers, plus DLC-coated internals for explosive power and durability. A mass-optimized layout and

Dell’Orto 1.73” (44mm) throttle body ensures razor-sharp throttle response, while the Athena ECU with GET Power Assist delivers advanced traction and launch control. 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 programmable engine management system. The Exedy clutch and 5-speed gearbox with Brembo hydraulics provide smooth, precise shifting, and the quickshifter enables clutchless upshifts from 2nd to 5th gear.
