2025 KTM 350 SX-F

With over a decade of racing - and winning - under its seat, the KTM 350 SX-F has long shed its underdog label and proven itself a worthy adversary. Delivering usable power throughout the rev range, unwavering stability at speed, and true championship-winning credentials, the 2025 KTM 350 SX-F is once again READY TO RACE.

Easy Suspension Adjustment

As 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.

Airbox

Designed 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 secure 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.

Serviceability

The 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.

More Usable Power

Perfectly filling the gap with the KTM 250 SX-F and the powerhouse KTM 450 SX-F, the lightweight KTM 350 SX-F powerplant weighs in at only 60.6 lb (27.5 kg). This makes it the ultimate weapon when weighing up power to weight options.

Absolute Control

Get ready for a full-on berm assault. The 2025 KTM SX and SX-F machines have received major frame updates directly from Factory Racing efforts. For starters, the frame area around the rear shock mount has been updated and made more streamlined, with new engine mounts and cut-outs for improved chassis flex. The front area of the frame is also updated. with a different wall thickness than the previous model year, with renewed engine mounts. This adds up to a 300g weight saving and improved flex for better cornering.
