Triumph Unveils New Enduro Models

Triumph might be best known for its street bikes, like the classic Bonneville, and adventure motorcycles, including the Tiger range. However, the brand is now expanding onto dirt trails with all-new enduro machines.

The TF 450-E and TF 250-E are competition-only dirt bikes developed in collaboration with enduro world champions Iván Cervantes and Paul Edmondson. With the motorcycles, Triumph aims to provide capable, nimble, and well-performing enduro bikes.

Uniting the two models is Triumph’s new aluminum spine frame, which boasts a low weight and optimized stiffness. It promises to deliver high-speed stability and great control and agility.

The motorcycles come into their own in other terms, however. Let’s take a closer look at both.

TF 450-E

The new TF 450-E draws its power from a 450cc liquid-cooled single-cylinder SOHC engine. This powerplant is capable of producing 57.8 ponies and 35.6 lb-ft of torque.

Triumph has incorporated titanium valves and an aluminum piston for consistent performance in high-rpm situations. Additionally, the gudgeon pin and rockers feature Diamond-Like Carbon (DLC) coatings for enhanced durability and lower friction.

An Athena engine management system with bespoke software helps the engine perform at its best in varying situations. With a press of an illuminated button, the rider can swap between two engine maps on the fly, choosing between aggressive performance and smoother control.

The engine is mated to a six-speed gearbox, which features a quickshifter. The one-directional quickshifter allows for clutchless upshifts from second to sixth gear.

Triumph has set the non-slip seat’s height at a tall 37.6 inches for both clearance and easy stand-up riding in technical sections. A 2.2-gallon fuel tank should last through several laps on the trail.

The suspension components come from KYB. In the front is a fully adjustable coil-sprung 48mm fork with 11.81 inches of travel. In the rear, suspension duties are handled by a KYB coil with three-way adjustability and 12.32 inches of travel.

For stopping the bike, it comes equipped with Galfer discs, 260mm in the front and 220mm in the rear. Gripping the discs are dual floating-piston front calipers and a single rear caliper, all from Brembo. The brake lever is adjustable.

In the tech department, the TF 450-E features an advanced traction control and launch control systems that affect rear-wheel slip and traction off the line. They’re controlled with illuminated handlebar clusters and a digital speedo.

The rubber on the 21-inch front and 18-inch rear aluminum wheels comes from Michelin in the form of the Enduro 2 tires. 

The TF 450-E is available to order, with deliveries starting in June 2025. It retails for $10,795.

TF 250-E

The TF 250-E uses many of the same components and tech as its larger-displacement sibling. Suspension, brakes, engine management system, transmission, tires, and rider aids are all shared between the two motorcycles.

Of course, the TF 250-E sports a different engine. This bike is powered by a 250cc single-cylinder DOHC powerplant that produces 41.7 ponies and 20.5 lb-ft of torque.

The 250-E also features a different exhaust system. It comes with a stainless steel exhaust with an integrated Helmholtz resonator (a side-resonator on the TF 450-E) in the header pipe.

Finally, the bikes are identical in looks and dimensions, although the TF 250-E is nearly six pounds lighter at 251.7 pounds vs. the TF 450-E’s 257.3 pounds.

The TF 250-E is likewise available for order at an MSRP of $9,795.
