The 2025 KTM 150 SX continues to represent one of the most exciting and unique offerings in the motocross world. Straddling the line between the ultra-lightweight 125 two-strokes and the heavier, more powerful four-strokes, the 150 SX delivers a rare combination of agility, responsiveness, and punch that makes it a favorite among riders who crave intensity without excess. KTM has once again refined this already impressive platform, offering a machine that remains true to its roots—lightweight, razor-sharp, and explosively fun—while integrating thoughtful updates that enhance performance, control, and rider confidence.

With its high-revving two-stroke engine now utilizing the latest in throttle body injection technology, the 2025 150 SX delivers more precise fuel metering, better throttle response, and improved consistency across a wide range of riding conditions. The engine’s explosive midrange and quick-revving character are ideal for aggressive riders who thrive on sharp bursts of acceleration and active, momentum-driven riding styles. At the same time, the improved fuel delivery system ensures cleaner running, smoother transitions through the rev range, and a broader powerband that makes the bike more tractable in tighter or slick conditions where throttle control is essential.

Equally important is the bike’s incredible handling. Thanks to its lightweight frame, advanced WP XACT suspension, and updated geometry, the 150 SX feels extremely nimble in corners, quick to respond to rider input, and stable when landing from jumps or powering through whoops. These characteristics allow riders to maintain higher corner speeds, maneuver effortlessly through technical sections, and stay in control even when pushing the limits. KTM has also made subtle improvements in rider ergonomics, helping reduce fatigue and improving rider connection with the bike over long motos or intense practice sessions.
