Triumph has revealed the 2027 TF 250-X, bringing revised engine calibration, updated KYB suspension settings, new Neken triple clamps and a series of clutch and gearbox durability updates to its 250cc motocross model. The bike is available to order now, with Australian pricing yet to be confirmed.
The changes follow a 2026 season in which Guillem Farres won the FIM MX2 World Championship aboard the TF 250-X, teammate Camden McLellan finished second and Triumph Factory Racing claimed the MX2 manufacturers’ title. Triumph says rider feedback, race data and testing from that program directly shaped the 2027 model.
Claimed peak output is unchanged at 47hp (35kW) at 13,500rpm, which Triumph says makes it the most powerful engine in the 250cc motocross class. For 2027 the engine calibration has been revised to improve throttle response, rideability and torque delivery, while a separate stop/start switch arrangement and new control switchgear have been added.
Engine management continues to run through an Athena ECU with GET Power Assist, a 44mm Dell’Orto throttle body and a Keihin injector, with a forged aluminium piston, titanium valves, DLC low-friction coatings and magnesium engine covers carried over.
The powertrain gains new valve guides for improved durability, along with revised gearchange hardware including a new selector drum and detent wheel, which Triumph says delivers cleaner, more precise shifts.
The clutch receives a new bearing, clutch pack and plates, working with the existing Exedy Belleville clutch to improve lever feel, engagement and consistency under repeated hard starts.
Suspension remains a KYB package comprising a 48mm Air-Oil Separation coil-spring fork and a three-way adjustable piggyback rear shock with a 50mm piston, both with revised settings for 2027.
New toolless adjusters have been fitted to allow faster trackside changes. The chassis gains new forged and machined aluminium Neken triple clamps, which Triumph says have been tuned for sharper steering and improved front-end feel, as well as a revised chain guide.
The aluminium spine frame with twin cradles, hydroformed swingarm, D.I.D DirtStar 7000-series rims, Pirelli MX32 mid-soft tyres and 960mm seat height are unchanged.
Standard equipment continues to include a Brembo braking system with Galfer discs, ProTaper ACF carbon-core handlebars and ODI lock-on grips. Launch control, traction control, a quickshifter and two switchable engine maps are fitted as standard, with traction control adjustable from the handlebar switch.
An optional Wi-Fi module and MX Tune Pro app unlock a further ten engine maps for adjusting power delivery, throttle response and engine braking.
Visually, the 2027 model is distinguished by all-black bodywork, updated graphics and redesigned fork guards.
The TF 250-X is a competition-only motocross model and is not road registrable. Pricing and local arrival timing are yet to be confirmed by Triumph Motorcycles Australia.
