KTM 300 SX

The KTM 300 SX is the ultimate expression of big-bore two-stroke motocross performance, delivering raw power and razor-sharp agility for riders who demand nothing less than dominance on the track. Designed for experienced racers, it offers the perfect balance of explosive acceleration, lightweight handling, and proven race-winning pedigree.
 Performance & Power At its heart lies a 293.2 cc single-cylinder, liquid-cooled two-stroke engine, producing class-leading horsepower and torque figures that translate to blistering straight-line speed and rapid corner exits. Equipped with electronic fuel injection and an advanced electronic powervalve system, it delivers both controllable low-end pull and ferocious top-end surge. The 300 SX features a close-ratio five-speed gearbox with precise Brembo hydraulic clutch actuation, ensuring seamless gear changes under heavy load. Electric start comes as standard, providing instant ignition and saving vital seconds in competitive scenarios.
Control & Comfort A lightweight chromoly steel frame with optimised stiffness ratios forms the backbone of the 300 SX, delivering exceptional cornering precision and straight-line stability. The WP XACT 48 mm AER front fork and WP XACT rear shock offer fully adjustable compression and rebound damping, enabling riders to tailor suspension to track conditions. Powerful Brembo braking components, paired with a 260 mm front and 220 mm rear disc, offer exceptional stopping power with superb modulation. The ergonomics package features a slim, contoured seat, optimised bodywork, and grippy contact points for maximum rider control and comfort.
Versatility & Style Visually, the KTM 300 SX carries the aggressive, factory-inspired styling synonymous with KTM’s championship-winning motocross range. Bold graphics, race-derived plastics, and a streamlined profile not only look the part but aid rider movement and aerodynamics. Practical technology, such as selectable engine maps, allows quick adaptation to varying terrain, while the minimalistic layout keeps the bike competition-focused. Equally at home on fast, flowing circuits or tight technical layouts, the 300 SX combines brute strength with refined handling, making it a formidable choice for riders chasing victory.
