2026 Triumph TF 450-E and TF 250-E Off-Road Models – First Look
Tue, 25 Mar 2025
Triumph officially revealed the 2026 TF 450-E and TF 250-E enduro models, adding two more off-road models alongside the TF 250-X and TF 450-RC Edition motocross bikes. Both enduro models will arrive in U.S. dealerships in June, with the TF 250-E starting at $9,795 and the TF 450-E starting at $10,795.
Developed with the help of five-time World Champion Iván Cervantes and four-time World Enduro Champion and Triumph Factory Racing Enduro Team Manager Paul Edmondson, the TF 450-E and TF 250-E are competition ready and set to race in the EnduroGP championship in April.
Both enduro models share the same lightweight aluminum spine frame design, similar bodywork, and premium suspension and brake components, with the engines being the main difference between them.
The TF 250-E is powered by a 250cc SOHC Single (pictured above), claiming it to be the most powerful engine in its class, citing an output of 41.7 hp and 20.5 lb-ft. of torque. Triumph claims the engine is perfectly suited for technical sections and tight enduro challenges. The engine is paired with a stainless steel exhaust system with an integrated Helmholtz resonator on the header pipe.
With the TF 450-E, Triumph says its DOHC Single offers a linear power curve for smooth acceleration in various conditions. The larger engine claims an output of 57.8 hp and 35.6 lb-ft. The 450 also uses a resonator, but it is housed in the silencer.
Both powerplants are managed by an engine management system co-developed by Triumph and Athena Industries. The software offers two engine maps that can be swapped on the fly, as well as traction control.
Unlike the motocross bikes and their five-speed transmissions, the enduro models are equipped with a six-speed transmission with an upshift-only quickshifter.
KYB provides the suspension system for both models. The front end uses a 48mm coil spring fork with adjustable compression and rebound and 11.8 inches of travel, while a linked rear shock allows adjustments for high- and low-speed compression as well as rebound and 12.3 inches of travel.
The braking system consists of Galfer discs and Brembo calipers, with a single 260mm disc and floating two-piston caliper up front, and a 220mm disc and single-piston caliper at the rear. The D.I.D DirtStar 7000 series aluminum rims come shod with Michelin Enduro 2 tires.
Other features for both models include Pro Taper ACF Carbon Core handlebars, ODI half-waffle lock-on grips, a 2.2-gallon fuel tank and a 37.6-inch seat height.
