2026 KTM 250 SX Base

Information

2026 KTM 250 SX

RELEASE THE RUCKUS

Think "unbridled 2-stroke performance" and you'll probably see a KTM 250 SX in your mind's eye. For good reason too - there isn't much to compare it to. The KTM 250 SX takes that even further making it even more of a legend and one deserving of the record books.

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
  • EFI + Power Valve

With EFI comes great rideability. Along with the electronic fuel injection and a power valve on the KTM SX models, allowing for more usable power throughout the rev range. Smoother power means better traction. Better traction means holeshot heaven!

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
  • Consistency

Count on a durable chain guide and chain guard and minimize the chances of hooking on external objects - especially in extremely muddy terrain while reducing dirt build-up around the swingarm and rear sprocket. For 2026 we've also modified the fixing points and routing of the wiring harness so it's less prone to wear and damage.
