The 2025 model carries the latest race look and graphics for the new season, with choices between #4 (Sexton) and #7 (Plessinger), making this FACTORY EDITION machine the closest riders and fans can come to the Pros, courtesy of a host of performance and practical upgrades.

The 2025 KTM 450 SX-F FACTORY EDITION is based on the technical platforms and READY TO RACE formula that has won world championships, a 450 MX Pro Motocross Championship, Grands Prix, Main Events and banked a host of podium trophies with a wide range of different athletes and riding styles. The 2025 creation will be the last KTM FACTORY EDITION of this current SX-F generation.

The 2025 machine features a light, compact and advanced single cylinder mass centralised engine. Cylinder, cylinder head, piston and crankshaft development ensure resistant, smooth, torquey and reliable power output with longer service intervals. The motor package includes an Akrapovic slip-on muffler, fully refined EMS and a 44 mm Keihin throttle body, as well as Pankl Racing 5-speed gearbox with quickshifter.

The robot-welded steel frame adheres to precise parameters of longitudinal and torsional flex for exceptional rider feedback, energy absorption, cornering confidence and straight-line stability for acceleration and braking. The structure is light and orientated around the anti-squat concept for a distinctive and effective handling sensation, thanks also to the light aluminum subframe. The chassis benefits from the latest specification fully adjustable WP XACT suspension (48 mm AER split air forks and 300 mm dual-compression control, tool-free rear shock with higher ground clearance to accommocate the linkage). A 7.2 litre fuel tank is incorporated into the carefully crafted rider triangle for ergonomics that permit precise control and grip of the bike in any condition.
