Triumph has added a brand-new TF 450-X to its 2026 motocross line-up, packing factory-level tech, updated componentry, and race-winning performance into its latest 450-class machine.
Following the debut of last year’s TF 450-RC, the new TF 450-X builds on the same race-developed DNA, making it available in a standard production model with a few fresh updates for 2026.
What’s New for 2026
- Exedy clutch hub with optimised lubrication ports for improved durability and torque capacity.
- Belleville Clutch Spring for more consistent, refined engagement in extreme racing conditions.
- Updated engine mounts to deliver more precise chassis feedback.
- New gearbox selector star for smoother gear changes and stronger engagement.
- Performance Yellow graphics kit with bold in-mould decals to make sure the bike looks as sharp as it rides.
Power and Performance
With 62.4hp at 9500rpm, Triumph claims the TF 450-X is the most powerful 450 motocross engine on the market. Paired with an ultra-light 108.3kg chassis, it delivers a class-leading power-to-weight ratio that translates directly into holeshot launches, responsive handling, and agile cornering.
Under the skin, the forged König piston, Del West titanium valves, DLC-coated cams, and magnesium engine covers highlight Triumph’s factory-level attention to detail. Add the Dell’Orto 44mm throttle body, Brembo hydraulics, and standard-fit quickshifter, and the TF 450-X is built to withstand punishment while remaining razor sharp.
Chassis and Handling
The TF 450-X continues with Triumph’s unique aluminium spine frame and hydroformed swingarm, tuned for stiffness, flex, and traction balance. The race-developed KYB suspension carries over from the RC edition, featuring a 48mm AOS coil spring fork and a fully adjustable shock refined for pro-level control in rhythm sections, heavy braking zones, and flat landings.
Brembo brakes, Galfer discs, lightweight D.I.D. rims, and Pirelli MX32 tyres come standard, completing a premium rolling package.
Race-Ready Spec
From the cockpit down, Triumph hasn’t cut corners:
- Neken yokes
- ProTaper carbon core bars
- ODI lock-on grips
- D.I.D 520 chain and JT sprockets
Electronics include launch control, traction control, dual maps, and full connectivity via the optional MX Tune Pro app, which unlocks up to ten extra maps.
Price and Availability
The 2026 Triumph TF 450-X is available now in Performance Yellow, starting from $15,790 race-away at Triumph motocross dealers across Australia.
For riders chasing podiums or weekend warriors who want the sharpest tool in the shed, the TF 450-X delivers a serious statement in Triumph’s push to dominate the 450 class.
