When it comes to power-to-weight ratios, the KTM 300 SX writes the rule book.
Now with learnings taken directly from the KTM Factory Racing teams, and a care package labelled “Go get ’em!”, the 2025 KTM 300 SX is engineered for one task alone – to lead from the front.
Electric Start
Selectable Maps
Electronic Fuel Injection
Easy Suspension Adjustment
Pre-mix gets a remix across the 2-stroke KTM SX range, with electronic fuel injection setting the standard.
Now there’s no more fiddly jetting setup pre-race, And thanks to the Keihin EFI and reed valve case design, you can be guaranteed of laying down optimal power at any altitude, all of the time
WP XACT SHOCK
Keeping things in check at the rear, the WP XACT rear shock has also undergone some changes for 2025 using settings directly from the KTM Factory Racing Teams The improved frame and shock geometry mean more ground clearance at the linkage, making it less susceptible to bottoming out. While we’re on the topic, smaller diameter linkage bolts save weight, while new linkage seals refine rear shock response and advanced damping characteristics.
Selectable Maps
The 2025 KTM 300 SX features a map select switch allowing the racer to switch between 2 engine maps. Map 1 provides a linear, predictable power delivery, while Map 2 gives it the full beans with crisp, explosive power output.
Stability
An upgraded rear brake pedal finds its way onto the 2025 KTM Motocross range, adding additional stiffness, bending resistance and braking feel to the overall package.
At the other end, a forged steering head connection and CNC-milled triple clamps, make for the perfect alignment of the fork tubes. This precise geometry of the fork clamps ensures highly responsive and smooth fork action – not to mention unwavering stability when charging across ruts and onto the podium.
