BACK ON THE ATTACK

It's back! After a 2-year absence, the 2025 KTM 150 SX is once again ready to tear into your favorite MX track. Get ready to experience what it feels like to be a marble launched from a slingshot. The KTM 150 SX pulls hard from the bottom, gallops in the middle, and sings at the top. Which is where it belongs.

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 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.

Start Strong
  • EFI + Power Valve

With EFI comes great rideability. Along with the electronic fuel injection and a power valve on the KTM 150 SX, 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 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.

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 2025 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 boasts new settings, which not only compliment the updated 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 air pump needed to adjust the fork's air pressure is provided as standard in the buy-pack.

Maintaining Momentum
  • Consistency

A new chain guide and chain guard result in improved durability and minimize the chances of hooking on external objects - especially in extremely muddy conditions while reducing dirt build-up around the swingarm and rear sprocket.
