Triumph Motorcycles enters the world of enduro by launching the “Tf 250-E” and “Tf 450-E” models. Featuring technical and design solutions specifically dedicated to responding to racing needs in the most extreme contexts as well as on the most technical routes
With new frames, engines, and high-performance components, Triumph Motorcycles has made its debut in the 250cc and 450cc enduro segment. The development process was guided by the expertise of internationally renowned off-road riders, including Spain’s Iván Cervantes and the UK’s Paul Edmondson. The result is the “TF 250-E” and “TF 450-E,” both derived from their motocross counterparts previously introduced in the racing sector, but redesigned where necessary to meet the unique requirements of enduro applications.
Key changes include 18-inch rear wheels, LED headlights, a larger fuel tank exceeding eight liters, and a side stand. Modifications also extend to engine and chassis tuning—particularly a more fluid and less aggressive power delivery compared to the motocross versions.
At the heart of the TF 250-E is a 250cc single-cylinder engine producing just under 42.5 horsepower and nearly 28 Nm of torque, reaching up to 12,800 rpm with a broad, linear power curve. This setup is optimized for highly technical sections and demanding challenges.
The TF 450-E, on the other hand, is equipped with a larger-displacement engine designed to deliver strong low- and mid-range torque, ideal for steep climbs, rough terrain, and racing situations requiring fewer gear shifts.
Both engines feature a 44mm Dell’Orto throttle body, Del West titanium valves, and a König forged aluminum piston to maintain consistent performance and high reliability while minimizing maintenance needs. A six-speed gearbox pairs with a racing-derived Exedy clutch capable of handling intense racing loads.
Electronic management, developed in collaboration with Athena, includes advanced mapping and traction control strategies. Riders can choose between two engine maps—one aggressive and one more controlled—with further customization available via the optional Wi-Fi-enabled Triumph “MX Tune Pro” app.
Each bike features a unique exhaust system: the TF 250-E uses Helmholtz resonators for optimized delivery, while the TF 450-E sports a model-specific silencer. Both produce a deep, powerful sound to match their performance.
The chassis is equally refined. A hand-welded TIG aluminum beam frame strikes a balance between rigidity and lightness. A low center of gravity and enduro-specific geometry ensure agile handling in tight sections and stability at high speeds. The specially designed swingarm improves front-end feel for maximum rider control.
For suspension, Triumph partnered with Kayaba to deliver top-tier performance across all terrains. The 48mm fully adjustable AOS forks and a rear suspension with optimized enduro linkage provide excellent shock absorption without sacrificing handling precision.
The Brembo braking system includes a 260mm front disc and 220mm rear disc for superior stopping power and modulation. Lightweight aluminum alloy wheels improve durability and reduce unsprung weight. These are paired with Michelin Enduro 2 tires for maximum grip across variable surfaces.
Additional features include an optimized launch control system, a quickshifter for smooth gear changes from second to sixth gear, advanced traction control, and backlit handlebar controls. Riders also benefit from a digital speedometer, an ergonomic anti-slip seat, and a customizable riding position thanks to Pro Taper ACF Carbon Core handlebars with adjustable mounts.
