The KTM 250 SX is KTM's two-stroke 250 cc motocross racer. It is light and powerful, and a two-stroke is simple and cheap to maintain. For 2025 it gets a reworked frame, updated suspension and new bodywork, along with KTM's electronic fuel injection for two-strokes. It's built for riders who want a race-ready bike straight off the showroom floor.
- Fuel-injected 249 cc two-stroke: Keihin EFI with a 39 mm throttle body and a Vitesco Technologies engine management system gives you smooth, controllable power with no premix needed.
- Light engine: the engine weighs only about 23.9 kg, making it a benchmark in the 250 class.
- Two selectable maps: Map 1 delivers power smoothly and predictably, and Map 2 makes it sharp and aggressive.
- Tool-free suspension adjustment: the WP XACT AER 48 mm fork has hand clickers, and the WP XACT shock has hand-adjustable high- and low-speed compression.
- Updated chassis: a hydroformed 25CrMo4 steel frame paired with a reinforced aluminum/polyamide subframe.
- Race hardware: electric start, Brembo hydraulic clutch and brakes, a DDS clutch, Neken handlebar, Excel rims and CNC-milled triple clamps.
