The 2026 KTM 250 SX-F stands out for its precision-engineered 250 cc four-stroke engine, designed to deliver strong, usable power across the rev range without sacrificing control. The lightweight single-cylinder layout, advanced Keihin EFI with a 44 mm throttle body, and refined engine management system work together to provide crisp throttle response, efficient fuel delivery, and consistent performance in demanding race conditions. Paired with a smooth 5-speed transmission and Brembo hydraulic clutch, the bike offers confident acceleration and effortless power transfer out of corners.

Chassis performance is another defining strength of the 250 SX-F. The central double-cradle 25CrMo4 steel frame is engineered for optimal flex characteristics, giving riders precise feedback and stability at speed. An aluminium-reinforced polyamide subframe keeps overall weight low while maintaining strength and durability. Combined with reliable disc brakes front and rear, the chassis delivers predictable handling, strong braking control, and the confidence needed to push hard on technical tracks.

Suspension is where the 250 SX-F truly shines in race environments. The WP XACT 48 mm AER front forks and WP XACT rear monoshock with linkage offer excellent bump absorption and balance, keeping the bike composed through ruts, jumps, and high-speed sections. With generous suspension travel and fully adjustable compression and rebound settings, riders can fine-tune the setup to suit track conditions and riding style. The result is a lightweight, agile motocross machine that feels planted, responsive, and ready to compete at a high level.
