2024 Triumph TF 250-X Technical Overview

Features and specifications of Triumph’s first 250F motocross bike.

The Triumph Motorcycles team has been working overtime. Since debuting the all-new TF 250-X to the motocross community at Gatorback Cycle Park near Gainesville, Florida, in February, it has successfully campaigned both the 2024 AMA Supercross 250SX East Region Championship and AMA Pro Motocross series. Promising results overseas in the FIM Motocross World Championship, where its title combatants have steadily increased their presence in the always competitive MX2 classification, adds more on-track knowledge and a strong base moving forward as well.

After a slight delay in receiving dealership units, Triumph is finishing off 2024 strong with more inventory and accessibility to the brand. With ambassadors like Ricky Carmichael and Jeff Stanton, along with highly experienced test riders in Ivan Tedesco and Clement Desalle, our Dirt Rider team was more than excited to see what this first-year bike had to offer. Phrased simply, it’s impressive—really impressive. Read on to learn more about the 2024 Triumph TF 250-X and what makes it one of the most unique 250cc four-stroke motocross bikes on dealership floors.

Triumph TF 250-X. Not just an all-new model, but an all-new brand to enter the motocross market. Motorcycles have changed quite a bit since Triumph introduced the Triumph 1 in 1902!Jeff Allen
The heart of all competitive 250F racers: a strong engine package. The TF 250-X features a fuel-injected liquid-cooled DOHC four-stroke 250cc single-cylinder engine. Compression ratio is 14.4:1 and rev limiter is set at a rather high 14,000 rpm.Jeff Allen
The DOHC cylinder head features finger followers to reduce valve train weight and Del West titanium valves. A plain bearing design is used on the connecting rod. Hydraulic clutch actuation is controlled by a Belleville spring.Jeff Allen
It’s all in the details, and Triumph brings its own flare to the 250F motocross bike market.Jeff Allen
The TF 250-X uses a close-ratio five-speed gearbox, and features magnesium clutch and ignition covers.Jeff Allen
Stepped head pipe protruding from the center port exhaust. A vertically integrated resonance chamber and louvers that extend to protect the aluminum radiators are nice touches.Jeff Allen
Technically a Helmholtz chamber, resonance chambers like this are gaining popularity in the four-stroke world.Jeff Allen
Paired with this repackable muffler, the TF 250-X emits a race-ready tone right off the dealership floor. Triumph’s accessories division already has a complete Akrapovič exhaust system for those who want a little extra oomph and lighter weight.Jeff Allen
Twin Air supplies the pre-oiled air filter. Removal is toolless, making maintenance all the easier for Triumph owners.Jeff Allen
Our testbike came equipped with a vented airbox cover, though Triumph includes a traditional solid cover for new buyers. Note the Torx bolt on the side panel: In an effort to save weight, Triumph utilized Torx for a large majority of the fasteners.Jeff Allen
A 1.8-bar radiator cap comes standard. Removal can get tight near the black plastic control cables guide, and we ended up modifying said plastic for easier fluid checks.Jeff Allen
Brembo supplies the hydraulic clutch and brake components. Adjustability is as easy as rotating the circular black knob. ODI clamp-on grips are standard equipment.Jeff Allen
Triumph TF 250-X electronics suite: launch control (LC), quickshift (QS), traction control (TC), and map switch (M). It gets rather bright when all are utilized!Jeff Allen
Engine start and stop buttons all-in-one on the throttle side, with an indicator light on top. We appreciate the larger size and shape of the red stop button. Also to note, no 8mm control lever adjustments: Torx all around to rearrange the throttle, front brake, and clutch lever positioning.Jeff Allen
KYB fork stickers are included with every new TF 250-X. Installing them when new will help protect the upper fork tubes of the KYB Air-Oil Separate (AOS) 48mm closed-cartridge coil-spring components. Spring rate is 4.7 Nm in both legs. Triumph offers 4.5 Nm and 4.6 Nm for lighter riders, as well as 4.8 Nm and 4.9 Nm rates for heavier riders.Jeff Allen
Fork height is 5mm in standard trim, and even the Neken triple clamps feature Torx bolts. Compression damping adjuster is in the center of the fork cap, with the bleed screw at the front.Jeff Allen
Quality KYB shock, which features spring preload, rebound damping, as well as low- and high-speed compression damping adjustments.Jeff Allen
A 56 Nm shock spring comes standard. Stock suspension setup should be ideal for riders and racers in the 165–185 pound range.Jeff Allen
Silver inset screw is low-speed compression damping, light brown 17mm nut is high-speed compression damping, and rebound damping screw is located on the bottom of the shock clevis. Spring preload is adjustable once the lock rings are freed: Don’t forget to tighten them back up!Jeff Allen
Hand-welded aluminum frames feature some of the cleanest lines around.Jeff Allen
Even the Triumph emblem is cast into the swingarm; little touches like this can be found throughout.Jeff Allen
The hydroformed swingarm of the TF 250-X is aesthetically unique. The 13mm nuts secure the rear axle adjuster bolts.Jeff Allen
Cutout aluminum head stay brackets, also affixed with Torx bolts.Jeff Allen
More Torx on the fork lug bolts and fork guard protectors. The KYB lugs are built tough. Fork rebound damping adjuster can be found on the underside of both lugs.Jeff Allen
Polished rear hub and two-cross-spoke pattern of the TF 250-X. Double-butted spokes are stronger and lighter than straight-gauge alternatives.Jeff Allen
Brembo front brake system secured with, you guessed it, Torx bolts. Twin 24mm pistons and a solid 260mm front rotor stop this Triumph in a hurry.Jeff Allen
A 220mm rotor in the rear, stopped by a single 26mm piston Brembo design. One can also spot the end of the steel-braided brake line from this angle.Jeff Allen
The Brembo rear brake master cylinder is protected by a black plastic guard, secured by two zip-ties. A perfectly indexed swingarm pivot bolt fits nicely into the aluminum frame.Jeff Allen
An adjustable brake stop is utilized to keep the rear brake pedal from hyperextending vertically and damaging the master cylinder internals.Jeff Allen
The Triumph TF 250-X comes equipped with a black D.I.D DirtStar 19 x 1.85 rear rim and Pirelli Scorpion MX32 Mid Soft rear tire in 100/90-19 sizing.Jeff Allen
JT Sprockets handles the 13/48 gearing. Indexing marks are unique on the TF 250-X; new owners would be wise to acclimate themselves as the stock chain stretches.Jeff Allen
The radiator shrouds are smooth and sleek, with underlaid graphics. They flank a 1.8-gallon gas tank. There’s only one visible fastener: an 8mm bolt at the top, near the gas cap. In our time with the bike, we also noticed 8mm front brake line guide bolts on the fork guards.Jeff Allen
Two Torx bolts secure the front of the radiator shrouds and help to strengthen the louvers as well. In the foreground, one can spot the tapered lower Neken triple clamp.Jeff Allen
Break-in instructions and rear fender warning labels. These are easily removable as they are not inlaid like a majority of the TF 250-X graphics. On the far left you can see the “AG” of an indicated sag line. Features like this take some guesswork out of where to measure when baselining your new bike and staying on top of sag.Jeff Allen
ProTaper ACF (aluminum/carbon fiber) handlebar comes stock. The 812mm width is wider than many OEM offerings, but the overall ergonomics package fits quite right. New owners should be pleased to see so many quality aftermarket parts included on every TF 250-X.Jeff Allen
Even this well-positioned hourmeter behind the front number plate is a thoughtful touch.Jeff Allen
Ready to shred and on dealership floors now, the 2024 Triumph TF 250-X exceeds expectations. A $9,995 MSRP gets you the latest design in the 250F market space.Jeff Allen
