KTM isn’t bashful about the racing success of its SX motocross line. Taking five AMA 450 supercross championships since 2015, 30 MX World titles since 2000, and eight MXGP crowns since 2010, Team Orange clearly knows what it takes to compete at the highest level. For 2023, KTM improves on that winning formula with the redesigned four-stroke and two-stroke SX models.
The motocross lineup still benefits from a hydro-formed, laser-cut frame, but the engineers improved longitudinal and torsional flex to enhance stability, energy absorption, and rider feedback. A new rear shock mount improves anti-squat behavior and the forged steering head connection amplifies feel and responsiveness at the front. Parallel frame mounts deliver extra rigidity on the two-stroke dirt bikes while rotating the engine rearward by two degrees centralizes mass on the four-strokers.
