Finding the right fit for your little ripper is easy thanks to height-adjustable suspension, handlebar position, subframe, and bodywork, taking the seat height from a low setting of 634mm to a taller setting of 682mm.
START STRONGThe 2025 KTM 50 SX FACTORY EDITION features a modern and compact engine using the latest 2-stroke technology. Using a 3-shaft design, the crankshaft is positioned near the center of gravity, which benefits mass centralization and creates the ideal intake angle into the reed valve for top-level performance. An independent cylinder blank allows for a complete cylinder design, with increased power.
CALM UNDER FIREWith a tank design to compliment the frame concept and bodywork, the KTM 50 SX FACTORY EDITION is ready to fuel the fire in your little ripper.
