Triumph Motorcycles officially launch the new TF 250-E and TF 450-E Enduro models – details of the all-new bikes and what the British manufacturer has to say about their eagerly anticipated new off-road machines.

The most eagerly anticipated new enduro motorcycles, not just all year but in years, Triumph have finally revealed the details of the two new models, the 2026 TF 250-E and TF 450-E.

What do you think of the colours and graphics? The family resemblance is there but Triumph has distinguished the enduro from the motocross models.

Developed entirely by Triumph using the immense skills of five-time World Champion Iván Cervantes and four-time World Enduro Champion Paul Edmondson, the TF 250-E and TF 450-E boast a brand-new engine platform, unique aluminium spine frame design and are equipped with Brembo brakes and KYB suspension components to position these new models right in the spearhead of new enduro bikes, before we've even turned a wheel.

The ‘comes with’ list is impressive and include an electric start, fan as standard, six-speed gearboxes, Athena engine mapping, an 8.3 litre (2.19 US Gal) fuel tank, that KYB suspension, the Brembo brake calipers biting on Galfer discs…it’s an impressive spec sheet.

There’s a lot to dig into here as Enduro21 finally gets the official details of the new models. We knew two bikes were coming, we kinda already knew what they would look like too with Jonny Walker more or less riding a replica in SuperEnduro this season, but now this is officially a first look at them both in all their glory.

Here’s what they have to say about their all-new enduro bikes...

The TF 450-E is obviously a bold move from Triumph in a world where, to an extent, the trend is to go smaller and lighter. The press information promises the 450cc motor will have “a linear power curve, smooth acceleration, greater low-end and mid-range torque, smooth, tractable power delivery and controllable, connected engine character ensure riders can feel the bike's rear wheel traction and transfer power to the ground.”

By contrast the new 250 enduro engine is boasting “the most powerful engine in its class, delivering responsive, manageable power with a purposeful character, perfectly suited for technical sections, tight enduro challenges, and ideal for riders seeking fun and accessible performance.”

No details are published yet on the power and torque from the 450 but the 250 has a claimed 42PS/41HP of power and 27.8Nm/20ft-lb of torque, with “a broad power curve and strong bottom-end” up to a top-end rev-limit of 12,800 RPM.

Different to the MX models

Both powertrains have been developed to have more inertia than the motocross engine, weightier cranks would be the obvious guess, which should provide a more stable, tractable power delivery for enduro conditions. 

Both have six-speed gearboxes matched to Exedy racing clutches, Athena ignition systems, electric start, fuel injection Dellorto 44mm throttle bodies also has an air bypass system for cold starts and a manually adjustable idle speed. Other details on the inside include Del West titanium valves and a forged König aluminium pistons.

Triumph say the TF 450-E also boasts the addition of Diamond Like Carbon (DLC) coatings on the gudgeon pin and rockers, which improves durability and reduces friction. The liquid-cooled engines come with auxiliary fans as standard and tool-free access and removal of the Twin-air filter.

Athena Management System – two engine maps

Triumph and Athena have combined to develop the engine management system for the TF250-E and TF450-E which features completely bespoke software for each bike. This system has mapping and traction control, specifically tailored by Triumph and Athena to enhance performance, reliability and presumaby rideability.

Two engine maps let you adapt performance for different conditions at the touch of a button, which Triumph says you can switch on the fly. One for aggressive performance, the other for smoother, more controlled delivery on technical or slick 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, which Triumph say aids cylinder evacuation and performance.

The TF 450-E features a side-resonator in the silencer, designed for targeted noise attenuation, resulting in a deep, powerful exhaust note.

Lightweight Aluminium Frame

Both models are built around Triumph’s own lightweight aluminium spine frame, developed by the boys Cervantes and Edmondson to deliver to right skills for enduro. Triumph say it dishes up the right mix of stiffness, low centre of gravity, agility, high-speed stability, and delivering sharp directional control and confidence.

KYB Suspension System and a different swingarm

The fully adjustable KYB coil-sprung 48mm forks and 3-way adjustable linkage-driven rear suspension (high and low-speed compression plus rebound damping) are specifically tuned for enduro. They feature a reduction of 10mm compared to Triumph’s motocross models and different settings for a better balance between handling and bump absorption, while minimising pitch during cornering, they add.

There’s also enduro-specific swingarm geometry on the EW models which they say creates more accurate front-end feedback, they say, helping the rider make quicker direction changes and “delivering intuitive, inspiring handling for both competition and adventure”.

Rider-focused technology

Both the new TF 250-E and TF 450-E models are equipped with handlebar-mounted controls featuring illuminated buttons for quick, easy adjustments, while the digital speedo screen provides real-time data, including engine temperature, trip information, and gear position.

The traction control system monitors rear-wheel slip and modulates power output to provide more consistent grip on unpredictable surfaces, and there’s a launch control which manages torque delivery to maximise traction off the line, if you’re into that kinda thing.

There’s even more here with a Triumph-designed quickshifter for seamless, clutch-less upshifts between second and sixth gear for uninterrupted power delivery and preserves momentum during race-critical sections.

Galfer discs, Michelin tyres, Brembo brakes…

More premium components, included as standard are the Galfer performance braking system with 260mm front brake disc and 220mm rear brake disc, Brembo twin 24mm piston floating front caliper, a single 26mm piston floating rear caliper and adjustable span brake lever.

Both models are fitted with Michelin Enduro 2 tyres, D.I.D DirtStar 7000 series aluminium rims, with a black anodised finish and Triumph-designed lightweight cast and machined aluminium hubs completes the look.

Pro Taper ACF Carbon Core handlebars with adjustable mounts enable riders to personalise the fit and feel and the bikes feature ODI half-waffle lock-on grips.

Ergonomics and Style

The ergonomics of the TF 250-E and TF 450-E have been tweaked compared to the motocross models for both performance and rider comfort.

A 955mm seat height is more manageable for technical sections plus there’s a non-slip Pyramid seat for grip and to improve positioning in both dry and wet conditions. The seat cover material is highly durable, they add and resistant to wear and tear.

By now we are getting used to the look of the Triumphs, developed and manufactured in-house with Triumph Performance Yellow, Black and White and magnesium engine covers.

The 8.3 litre fuel tank provides a longer range for extended riding, and there are of course the integrated LED lights.

Global dealer network already established

Building on Triumph’s established reputation and dealer network, the new models are backed by a global network of specialist dealers and a 24/7 parts ordering and supply system.
