Triumph Motorcycles reveal the first of their much-anticipated off-road model range, the TF 250-X – Enduro21 looks at the details, specifications and gets busy second-guessing what the enduro bike might look like…

It feels like the longest tease in motorcycle history but Triumph Motorcycles have finally revealed the details, specifications and prices for the first what will become an extensive off-road range, the TF 250-X.

Forgive us our little bit of photoshopping of the main image here, we wanted to see what the new motocross model announced today would look like with lights on. Not bad, hey?

For the time being we’ll have to wait for the enduro version, just as we’ll be waiting for a TF 450-X model “later in 2024” Triumph say. In the meantime, feast your eyes on the details and specifications.

Triumph TF 250-X technical highlights:

  • DOHC, four stroke single with forged aluminium piston, titanium valves, diamond-like carbon low friction coatings, magnesium engine covers and Exedy Belleville clutch
  • Unique aluminium chassis
  • All-new electronic engine management plus optional accessory MX Tune Pro app for on-the-go adjustability
  • Sifferent map options, traction control, launch control and quick shift options
  • Brembo brakes system
  • KYB fully adjustable suspension front and rear with linkage rear type
  • D.I.D. Dirt Star rims
  • Pro Taper handlebars
  • $9995/£9795/€11,395/$11,495 (CAD)
  • TF 450-X and Enduro range to follow later in 2024
  • Order online for click and collect or via new dealer networks globally

“The most complete specification package ever to launch into the ultra-competitive 250cc motocross market” Triumph are saying about their dirt bike. It’s big talk but this is a big deal from a manufacturer who clearly have designed and built a bike which is a complete package.

People in the know, who have been testing the bikes for a while now, have told Enduro21 more than once over the last year or more that the new Triumphs are the real deal and aren’t just here to make up the numbers. We can see now that wasn’t just BS.

“This bike is 100% Triumph, conceived, designed, developed and manufactured by our world leading chassis and engine teams, with expert support from our racing champions.” Says Triumph Motorcycles’ Chief Product Manager, Steve Sargent. “We started with a blank sheet of paper and began an all-new ground-up design, including a new engine, new chassis and new electronics.”

“Racing Champions” means Ricky Carmichael and Iván Cervantes, but we also know a lot of testing has been going on in the UK with a certain Paul Edmondson and a gang of riders stacking up thousands of hours mileage testing the bikes.


The press information is littered with superlatives but it’s hard not to be impressed with the specifications (in detail below) which include a “unique”, ultra-compact aluminium chassis which weighs in at a claimed 104kg.

That list of components including KYB suspension, Brembo brakes, DID Dirt Star rims is a quality one from the market which puts it in a very strong position. Aftermarket accessories already on the available shopping list include an Akrapovic exhaust.


The graphics and plastics help it look slim and we can see hints of other manufacturers machines in the TF 250-X. The bold distinctive Triumph Racing Yellow and black graphics scheme will surely make it stand out.

A new Triumph network of specialist motocross dealers, will be offering sales, servicing, parts and a new dedicated range of apparel, backed by a mobile-optimised 24/7 online parts supply system, so customers can order for express delivery, straight from the track.

Here’s what else Triumph have to say about the TF 250-X

Performance Racing Powertrain

Triumph has developed an all-new performance racing powertrain, a competition four stroke single, that is ultra-compact and super light. With a forged aluminium piston and titanium valves, the engine also has diamond-like carbon low friction coatings, lightweight magnesium covers and an Exedy Belleville clutch.

Advanced engine management and tunability is complemented by the optional accessory MX Tune Pro app, enabling riders to use real-time user selectable mapping, a real-time engine sensor dashboard and live diagnostic functionality, through a controlled programmable engine management system.

Aluminium Chassis

The unique aluminium chassis has a high strength, lightweight spine frame with twin cradles, designed for the optimum balance of performance, mass and flexibility. The total weight of the bike will see the new TF 250-X set a new benchmark for the best ‘power-to-weight’ ratio in the category. It also delivers a high level of tunability to suit different riders and styles.

Top Tier Specification

The TF 250-X features premium, top tier componentry throughout, adding up to an unrivalled specification for a production bike in this category. KYB suspension tops the list, with 48mm AOS coil forks, forged and machined 7075-T6 aluminium triple clamps and a three-way piggyback coil rear shock.

The premium Brembo braking system features twin 24mm piston floating front caliper, a single 26mm piston floating rear caliper and Galfer 260mm front and 220mm rear discs. DirtStar 7000 Series aluminium rims and machined aluminium hubs are fitted with Pirelli Scorpion MX32 mid-soft tyres. Pro-Taper ACF carbon core bars and ODI half-waffle lock on grips complete the set up.


Competition Accessories

In addition to the high level of specification already included as standard, Triumph has worked with the biggest, premium brands to create a dedicated range of competition accessories to further enhance performance and capability. 

Accessories include:

  • Akrapovič full titanium exhaust system
  • XTrig hole shot device
  • Athena LC-GPA launch control module with rider-selectable enhanced traction control and launch control settings and LED engine speed indicator
  • MX Tune Pro wi-fi module
  • Performance gripper seat and seat cover
  • Bodywork replacement kit

Triumph’s Motocross dealer centres will also be stocking a new clothing range, available side by side to the new TF 250-X. Launched by Triumph in partnership with Alpinestars, the range includes Motocross and Enduro boots and apparel.

Specialist Triumph Off-Road Centres
