The Triumph TF 250-X motocrosser received a few updates for 2026. The most notable is a brand-new airbox and silencer redesigned to enhance airflow. Along with updated engine mapping, these changes lead to “improved power delivery and throttle response,” says Triumph.
The ’26 is equipped with a new Exedy clutch that Triumph says “delivers a more direct engagement, enhanced durability under extreme conditions, and significantly increases torque capacity.”
Updated suspension tuning focused on improving mid-stroke control, chassis balance, and cornering stability.
Details include a new layout for the battery tray for better accessibility and a redesigned oil level sight glass for clearer and more accurate readings. And, it goes without saying, it has new graphics.

The following is from Triumph’s press release:
The updates include an all-new airbox and silencer to maximize airflow, with enhanced engine mapping to deliver improved power delivery and throttle response, plus updated suspension tuning and a new Exedy clutch.
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 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.
Steve Sargent, Chief Product Officer, Triumph Motorcycles: The TF 250-X has already made a huge impact in the motocross world, delivering podium-finish performances in the 2024/2025 Supermotocross Championship, as well as the MX2 class in MXGP. This TF 250-X, built for 2026, is the result of relentless development and feedback from our factory riders. With sharper power delivery, refined suspension, and advanced electronics, it’s built to give riders the edge they need to win.
“These updates will help all riders to make the most of the available torque, improving the feel, acceleration and response, so it is even more competitive. The new Exedy clutch and enhanced engine calibration will be compelling reasons for fans to try the Triumph ready for the upcoming season.”
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 ensure 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 clutch-less upshifts from 2nd to 5th gear.
Race-Ready Suspension
The unique aluminum chassis has a high strength, lightweight spine frame with twin cradles, designed for the optimum balance of performance, mass and flexibility. Paired with a hydroformed swingarm, the chassis is designed for optimal flex and rear grip.
The race-developed linkage system which ensures consistent suspension performance, has been tuned to deliver improved mid-stroke control, better chassis balance and enhanced cornering stability. This high-performance setup is completed by KYB 1.89” (48mm) AOS coil forks, forged and machined 7075-T6 aluminum triple clamps and a three-way piggyback coil rear shock.
Top-Tier Specification
The TF 250-X is equipped with premium, race-proven components throughout, delivering a specification straight out of the crate that is unmatched in a production motocross bike.
At the heart of its stopping power is a high-performance Brembo braking system, featuring twin .94” (24mm) piston floating front calipers and a single 1.02” (26mm) piston floating rear caliper. With a 10.24” (260mm) Galfer wave disc at the front and 8.66” (220mm) disc at the rear, the system delivers precise, controlled braking in all conditions.
Lightweight DirtStar 7000 Series aluminum rims are paired with machined aluminum hubs and wrapped in Pirelli Scorpion MX32 mid-soft tires, offering exceptional grip and durability on race surfaces. For rider control and comfort, the TF 250-X features ProTaper ACF carbon core handlebars and ODI half-waffle lock-on grips, delivering a factory-level feel.
Advanced electronics elevate the riding experience further, with Launch Control (adjustable via handlebar or app), Traction Control, Dual Engine Maps for adaptable power delivery, a Sensor Dashboard displaying live data and diagnostics, and an Integrated Hour Meter for precise engine tracking.
