2026 Ktm SX 50

WINNING STARTS HERE.

The journey starts here. The first prime platform in the KTM Sportminicycle range will satisfy any youngster's thirst for fun, speed, adventure and that unquenchable desire to learn. The KTM 50 SX is built around an advanced steel frame, housing a powerful engine, an updated WP XACT AER fork, a WP XACT monoshock, and a new, advanced hydraulic Formula brake system. Reliability, durability and READY TO RACE aesthetics and spirit means it is the only choice for small kids and the big ones too!

HIGHLIGHTS:

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.

AIRBOX / FILTER The airbox features a conventional suction sleeve made from a hard-wearing polyamide instead of rubber and a Twin Air filter mounting system that features snap locks for easy and intuitive mounting. The Twin Air filter is also placed under the seat and is easily accessible without any tools by simply removing the seat. It also features improved dirt intrusion resistance, with no more dirt falling into the intake tract when changing the filter.

PERFORMANCE The KTM 50 SX 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 not only benefits mass centralization but also creates the ideal intake angle into the reed valve for top-level performance. For 2026, the transmission shafts are new developments with wider dimensions and several components have been reinforced to enhance durability.

WHEELS / TIRES Rolling off the race rig and into the pit lane, the KTM 50 SX uses lightweight, black anodized, aluminum rims just like the full-size KTM SX range. These provide the highest levels of strength and reliability, while MAXXIS MX-ST tires deliver outstanding performance on any terrain, along with exceptional straight-line stability.
