2025 Ktm SX 50

WINNING STARTS HERE.

When the next step up is into the 50cc class, there is no better option than the most powerful 50cc out there. For 2025, the KTM 50 SX is built around an advanced steel frame, housing a powerful engine, a 35mm WP XACT AER fork, a WP XACT monoshock, and an advanced hydraulic Formula brake system. Simply put - it's the most advanced and READY TO RACE 50 cc mini-crosser available to your little racer.

ADJUSTABILITY Different adjustability options were built into the 2025 KTM 50 SX construction using scientific statistical data and young racer's input data. 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 24.9 in / 634 mm to a taller setting of 26.8 in / 682 mm.

IGNITION A new digital ignition from Hidria finds its way onto the 2025 KTM 50 SX, with improved processing power and an all-new ignition curve, making for a cleaner burn and smoother power delivery.

PERFORMANCE Featuring the latest in 2-stroke technology, the 2025 KTM 50 SX. Using 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 completely new cylinder design, with increased power.

TANK The KTM 50 SX is ready to fuel the fire in your little ripper with an updated tank design to compliment the new frame concept and bodywork.
