2026 KTM 250 SX-F

THE FIGHTER IN THE ORANGE CORNER

The KTM 250 SX-F is a truly user-friendly package engineered to satisfy all riders, from novice to pro. But don't for one second think that makes it compromised - it is undisputedly READY TO RACE at any level. Delivering a power punch, and an optional electronic uppercut in reserve, the KTM 250 SX-F is ready to take on the 250 cc class and deliver a knock-out.

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

Weighing in at a lightweight 57.5 lb (26.11 kg), this mid-weight powerhouse churns out a remarkable payload, making it the undisputed performance leader in the 250 cc 4-stroke class. The engine in the KTM 250 SX-F has also been carefully designed and tuned to best suit the performance and handling characteristics of the overall package, bumping up power in the mid-range and the top-end.

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.
