Triumph reveals updates for the TF 250-X motocross 2026 model with new airbox and silencer to meet noise restrictions, a newExedy clutch, updated suspension settings and fresh graphics.

Already in its second year on planet earth, the Triumph TF 250-X has undergone a series of development updates to improve power, handling meet noise restrictions, and a some user-friendly changes for the 2026 model.

The headlines here are an all-new airbox and silencer to improve airflow they say but also to meet new npoise restrictions at FIM and AMA racing level, with new engine mapping to suit which improves power delivery and throttle response, plus updated suspension settings to improve mid-stroke and cornering handling and finally a new Exedy clutch.

Triumph say the updates to the airbox and end can are engineered to meet the new FIM and AMA race sound regulations, designed to keep performance but hit the noise requirements and maintain Triumph’s signature engine note.  

The changes mean a new ECU map setting which they claim improves power delivery and throttle response across the entire RPM range, helping quicker launches and corner exits.

The new performance Exedy clutch delivers more direct engagement Triumph says, helping in these same areas of performance plus it promises to be more robust and have “significantly increased” torque capacity.

Updated suspension settings improve mid-stroke control to help the bike’s chassis balance and cornering stability.

Other updates include a new layout for the battery tray to improve accessibility, and the oil level sight glass has been redesigned to help visibility. 

The new in-mould graphics scheme for 2026 uses the distinctive Triumph Performance Yellow on black again and makes a subtle difference we are saying.

The updates build on the TF 250-X’s successful 2023 debut, a bike developed in close collaboration with motocross legend Ricky Carmichael and World Enduro Champion Iván Cervantes (Enduro21 caught up with Ivan recently, read it here: Interview: Ivan Cervantes talks Triumph Enduro project and what’s next: a 350? A rally version?).

Triumph Motorcycles’ Chief Product Officer, Steve Sargent, says: “The TF 250-X has already made a huge impact in the motocross world, delivering podium-finish performances in the 2025 AMA Supercross 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.”
