With 5 AMA 450 Supercross titles in the last 7 seasons, the 2025 KTM 450 SX-F rolls up to the starting gate already armed with the learnings of past championships - only this time, it's freshly loaded with an all-new arsenal of weaponry.Features may include:BEFORE THE GATECLICK INTO ACTIONEasy Suspension AdjustmentAs always, the suspension boasts an easy tool-free setup at both ends, ensuring you chase down the podium in total control. On the rear, a hand-adjustable dual compression control allows riders to adjust high- and low-speed settings in a matter of seconds. The forks on the front end are also easily adjusted thanks to hand-adjustable clickers on the bottom of the fork shoe and top cap.BREATHE EASYAir filter boxDesigned to provide maximum airflow, the air filter box is designed with precisely positioned inlet ducts aimed at preventing air deformation and maintaining filter protection. The Twin Air filter and air filter support design feature a simple fail-proof mounting system for safe and accurate filter installation, ensuring the air filter is easily accessed, without tools, by removing the left side panel, for easy track-side maintenance. A vented air filter box cover is also included for all SX and SX-F models in the by-pack. LESS FOCUS ON THE TOOL, MORE FOCUS ON THE TRACKServiceabilityThe 2025 KTM SX and SX-F range is engineered and designed to provide riders with easy-to-access service parts, as well as suspension adjustability. This allows faster track-side and off-season maintenance, as well as making motocross more accessible for novice riders without pit crews.

The 2025 KTM 450 SX-F boasts one of the most manic 4-stroke powerplants in the paddock, with its SOHC engine proving to be the perfect example of advanced engineering. With a peak power output, and an overall engine weight of only 26.8 kg, you'll leave the competition with more than a little mud on the face.DROP THE CLUTCHLaunch Control & QuickshifterLaunch control, ENGAGED! Designed for the holeshot, the 2025 KTM SX-F range comes standard with launch control and Quickshifter function, allowing for fast upshifts without using the clutch. Launch control is easily engaged by pressing the traction control and Quickshifter buttons simultaneously and works by limiting the amount of power to the rear wheel, improving traction, and preventing loss of control under hard acceleration.
