Latest KYB Suspension
Updated MY27 suspension settings are paired with new toolless adjusters for fast trackside tuning. New fork guards add protection, while the premium KYB package delivers improved balance, damping control and rider feedback.
Upgraded Clutch & Gearchange
The clutch pack and gearchange received extensive updates, including a new gear lever, selector components, and detent system. The updates deliver cleaner shifts, improved engagement feel, and greater durability under race loads.
50-Tooth Final Drive
A new 50-tooth final drive and chain guide sharpen acceleration and improve drive out of corners, helping transfer the TF 450-X’s race-developed power to the rear wheel with confidence.
Bold All-Black Design for MY27
New all-black bodywork, fresh graphics, and Triumph Racing Yellow accents give the MY27 TF 450-X a focused factory-racing identity, complemented by separate stop/start switches and refined detailing.
Refined 450cc Power Delivery
Torque delivery, rear-wheel connection, and high-RPM stability are more refined because of updated valve guides, rocker shafts, and engine calibration. This offers riders stronger drive and greater control across demanding motocross terrain.
