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.

    Highlighted Features
    • 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.
    • 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!
    • 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.
    • Updated Suspension Settings: For 2025, the KTM SX and SX-F range has given the WP XACT AER fork and WP XACT rear shock an update. This means you'll be lining up at the starting gate with re-tuned settings, reduced weight, improved weight distribution, and an increase in overall response.
    • 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.
