    KTM 125 SX 

    The KTM 125 SX is a high-performance two-stroke motocross machine crafted for riders seeking a powerful, lightweight weapon for competitive riding. With full READY-TO-RACE pedigree and fuel-injection technology, it delivers exhilarating performance in a compact, agile package that excites and rewards ambitious racers.​​

     Performance & Power Under the slim plastic is a 124.8 cc liquid-cooled, two-stroke single-cylinder engine with electronic fuel injection via a 39 mm throttle body and an advanced powervalve system. This rev-happy unit is paired with a six-speed gearbox and a wet multi-disc clutch actuated by Brembo hydraulic system, enabling sharp throttle response and seamless gear changes. Electric start and selectable engine maps add modern convenience and versatility. Its ultralight engine (just 17.9 kg) delivers accessible yet raucous two-stroke power, making it superb for refining throttle and clutch skills.
    Control & Comfort Built on a chromoly steel central-cradle frame with a lightweight, reinforced polyamide subframe, the 125 SX weighs just over 92 kg wet. Its suspension includes a 48 mm WP XACT AER front fork providing 310 mm of travel and a WP XACT rear shock with 300 mm, all featuring tool-free adjustment for rapid setup. Braking comes from high-spec Brembo discs—260 mm front and 220 mm rear—mounted on a 21-inch front and 19-inch rear wheel setup, offering sharp stopping power and responsive handling.
    Versatility & Style Sporting authentic Factory Racing graphics and clean, ergonomic bodywork, the 125 SX mirrors its full-size siblings with bold aesthetic and functional design. Features such as electric start, selectable engine maps (for tuning throttle response to terrain), and modern chassis updates from factory racing enrich usability and performance. Its nimble nature and low overall weight make it equally suited for competitive race settings, advanced training environments, or intense club track use where agility and precision matter most.
