2026 KTM 350 SX-F

MIDDLE-GROUND MASTERCLASS

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 KTM 350 SX-F is once again READY TO RACE.

Features may include:

Before The Gate
  • 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 option allows riders to adjust high- and low-speed settings in a matter of seconds. The forks on the front end are also easily modified thanks to hand-adjustable clickers on the bottom of the fork shoe and top cap.

Start Strong
  • 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 60.6lb (27.5 kg). This makes it the ultimate weapon and the easiest choice for power to weight options.

Calm Under Fire
  • Absolute Control

Get ready for a full-on berm assault. The KTM SX and SX-F machines received major frame updates directly from KTM Factory Racing efforts. For starters, the area around the rear shock mount is streamlined, with engine mounts and cut-outs for improved chassis flex. The front area of the frame has an optimum wall thickness with renewed engine mounts.

Hit The Big Stuff
  • WP XACT Fork

Let's get the technical parts out of the way first; the 48 mm WP XACT AER forks fitted to the KTM SX and SX-F line-up features a capsulated air spring and pressurized oil chamber for progressive and consistent damping, while oil and air bypasses reduce pressure peaks. In combination with the mid-valve damping system, all this provides exceptional feedback and rider comfort. The fork also has settings which not only compliment the frame and rear linkage, but ensures stellar performance at all levels. Speaking of settings, these are easily adjusted via a single air pressure pre-load valve, as well as easy-access click adjusters for compression and rebound. Additionally, the WP air pump needed to adjust the fork's air pressure is provided as standard in the buy-pack.

Maintaining Momentum
  • Ground clearance

The shock absorber geometry on the KTM SX and SX-F machines gives decent ground clearance for the linkage, with the topology-optimized die-cast footpegs being less susceptible to hooking on deep ruts, and take-offs when scrubbing.
