Providing 41.7 HP (42.3 PS) of power and 20.5 ft-lb (27.8 Nm) of torque, with a broad power curve and strong bottom-end, the TF 250-E excels in slow-speed technical sections and drives through to a powerful top-end at 12,800 RPM.

Both powertrains have been developed to have more inertia than the motocross engine, providing a more stable, tractable power delivery across diverse, unpredictable race conditions. This is complemented by the six-speed Exedy racing clutch, which allows smooth, clutch-less upshifts, maintaining momentum in tight, technical sections.

Advanced fuel injection and ignition systems manage power efficiently, ensuring instant throttle response and reliable performance throughout demanding rides. A bespoke Dellorto 1.7” (44mm) throttle body provides an air bypass system for cold starts and a manually adjustable idle speed. Del West titanium valves and a forged König aluminum piston ensure consistent performance during prolonged high-RPM operation, significantly reducing servicing requirements.

For the TF 450-E, the gudgeon pin and rockers are further enhanced with Diamond Like Carbon (DLC) coatings, which improves durability and reduces friction. The high-capacity radiator and auxiliary fan combined with tool-free Dual-stage filter provided by Twin-air, provide consistent engine cooling, ensuring reliable power delivery on long, demanding rides.

Triumph and Athena have combined their extensive off-road experience to create a perfect synergy, resulting in the development of new software strategies with a strong emphasis on drivability and tractability. The engine management system for the TF 250-E and TF 450-E features completely bespoke software. This new system benefits from co-developed mapping and traction control strategies, specifically tailored by Triumph and Athena to enhance performance and reliability.

Dual Engine Maps adapt performance for different conditions at the touch of a button giving riders the edge to adapt and excel in varying race conditions. Riders can switch between two distinct engine maps on the fly. One for aggressive performance, the other for smoother, more controlled delivery on technical terrain. Additional maps can also be added with the optional Wi-Fi module and the Triumph MX Tune Pro app.

The lightweight stainless steel exhaust system on the TF 250-E boasts an integrated Helmholtz resonator in the header pipe, enhancing cylinder evacuation and performance. The TF 450-E features a side-resonator in the silencer, specifically designed for targeted noise attenuation, resulting in a deep, powerful exhaust note.

Both models feature Triumph’s unique, lightweight aluminum spine frame, with optimized mass, stiffness, and a low center of gravity. This provides exceptional agility, enhanced high-speed stability, and delivers sharp directional control and confidence. Post-fabrication machining enhances dimensional accuracy while the frame also features in-house hand TIG-welded craftsmanship.

The fully adjustable KYB coil-sprung 1.9” (48mm) forks and 3-way adjustable linkage-driven rear suspension are specifically tuned for Enduro challenges, ensuring responsive control, excellent power transfer and maximum traction in demanding conditions. With a reduction of .4 inches (10mm) compared to Triumph’s motocross models and enhanced settings, it offers an outstanding balance between handling and bump absorption, while minimizing pitch during cornering.

Easy to set up and service, this market-leading suspension offers high-level adjustability for rider weight and riding style, and exceptional tunability for varying terrains, from muddy tracks to rocky paths.
Enduro-specific swingarm geometry ensures accurate front-end feedback, which empowers riders to make rapid adjustments to navigate obstacles, and delivers intuitive and inspiring handling for competition.

Ensuring the new TF 250-E and TF 450-E are best-in-class, both models are equipped with an impressive selection of premium brand specification and cutting-edge technologies, optimizing performance in all conditions.

These can be accessed using intuitive handlebar-mounted controls featuring illuminated buttons for quick and easy adjustments, while the digital speedo screen provides real-time data, including engine temperature, trip information, and gear position. The advanced traction control system monitors rear-wheel slip and modulates power output to provide consistent grip on unpredictable surfaces, while the optimized launch control manages torque delivery to maximize traction off the line, helping riders achieve consistent, competitive starts. The Triumph-designed quickshifter enables seamless, clutch-less upshifts between second and sixth gear for uninterrupted power delivery and preserves momentum during race-critical sections.

More premium components, included as standard, include the Galfer performance braking system with 10.2” (260mm) front brake disc and 8.7” (220mm) rear brake disc, combined with Brembo twin .94 “(24mm) piston floating front caliper, a single 1.02” (26mm) piston floating rear caliper and adjustable span brake lever.

Both models are fitted with Michelin Enduro 2 tires, featuring an innovative tread pattern that provides better grip and traction, designed for diverse terrains (soft to hard) and conditions (mud to dry). The D.I.D DirtStar 7000 series aluminum rims, with a black anodized finish and Triumph-designed lightweight cast and machined aluminum hubs completes the look.

Built for the demands of competitive endurance racing, the ergonomics of the TF 250-E and TF 450-E have been designed to maximize both performance and rider comfort. Pro Taper ACF Carbon Core handlebars with adjustable mounts enable riders to personalize the fit and feel, perfecting the positioning between the handlebar, seat, and footpegs. This can minimize fatigue, enhance control during sharp turns, and reduce rider strain during prolonged standing. The ODI half-waffle lock-on grips offer exceptional hold and durability, ensuring control in all conditions.

A 37.6” (955mm) seat height provides optimal clearance while maintaining a manageable stand-over for technical sections while a non-slip Pyramid seat offers excellent grip and a rubbery consistency to improve positioning in both dry and wet conditions. The ergonomic design and high-quality foam padding provide superior comfort, allowing racers to ride longer without discomfort. The seat cover material is highly durable and resistant to wear and tear, making it ideal for off-road conditions. Tough, purposeful, and unmistakably race-ready, both Enduro models are styled with sharp lines and an aggressive stance. They feature aggressive, minimalistic bodywork, developed and manufactured in-house by Triumph to be lightweight and durable. Racing-inspired graphics in Triumph Performance Yellow, Black and White and magnesium engine covers, which also make trackside servicing easier, complete the look.

The 2.2 gallon (8.3 liter) fuel tank provides a long range for long laps, and the compact, integrated LED lights enhance visibility in low-light conditions.
