2025 KTM 50 SX
WINNING STARTS HEREWhen 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.
Features may include:
BEFORE THE GATE- Adjustablity
Different adjustability options were built into the 2025 KTM 50 SX construction using scientific statistical data and young racers' 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 634mm to a taller setting of 682mm.
START STRONG- Performance
The 2025 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. An independent cylinder blank allows for a completed cylinder design, with increased power.
CALM UNDER FIRE- Tank
The KTM 50 SX is ready to fuel the fire in your little ripper with a tank design that compliments the frame and bodywork.
HIT THE BIG STUFF- Wheels & Tires
Rolling off the race rig and into the pit lane, the 2025 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.
MAINTAINING MOMENTUM- Exhaust
The exhaust system, features the same manufacturing process as the full-size 2-stroke KTM SX range, with improved overall quality and performance. This has resulted in massive improvements in thermodynamics. Moreover, improved sealing of the silencer end cap and a rubber between the header pipe and silencer adds another level of quality to the exhaust system. The silencer comes with a black anodized finish and a signature 'Braaaaap!'.
