    KTM 50 SX

    The KTM 50 SX is a serious, race-ready youth motocross bike designed for young riders aged roughly 4 to 10. With true READY-TO-RACE DNA, it brings full-size MX performance into a miniature, adjustable package built to grow as confidence and skill develop.

    Performance & Power The heart of the 50 SX is a race-bred 49 cc two-stroke single-cylinder engine that delivers around 5.5 hp in a compact and responsive unit. The engine is liquid-cooled and tuned with a Dell’Orto carburettor and centrifugal multi-disc clutch, ensuring smooth, narrow-powerband acceleration without the need for a manual gearbox—perfect for budding racers. Its high-revving character delivers thrilling bursts of power with precise clutch feel that suits competitive riding.
    Control & Comfort Built on a lightweight chrome-moly steel frame, the 50 SX features both adjustable handlebar position and left-foot pegs to match growing riders. The front end is governed by a 35 mm WP XACT USD fork with around 200 mm travel, matched by a fully adjustable WP XACT rear shock with approximately 190 mm travel—offering plush yet responsive suspension. Hydraulic disc brakes front and rear deliver confident and controllable stopping power, while a low seat height and slim ergonomics encourage proper rider stance and easy handling.
    Versatility & Style Styled like its full-size KTM counterparts, the 50 SX carries bold FACTORY-RACING graphics, slim bodywork, and a textured seat designed for grip when standing. Though simple in its technology, it offers thoughtful details like air-box accessibility and a user-serviceable layout made for hands-on learning. Lightweight and agile, this bike is ideal for track days, motocross training, first-time competition, or just building confidence—making it a versatile choice for aspiring young riders.
