About this model
About the Ktm 250 SX
The KTM 250 SX is a pure two-stroke motocross bike in the 250 cc class, for decades one of the most successful race machines in motocross. The single-cylinder two-stroke engine produces around 67 hp through a manual gearbox and sits in a CrMo steel frame with fully adjustable WP XACT suspension. The bike is not road-registered and is ridden exclusively in competition or on private land.
The 250 SX targets serious motocross riders and competition pilots who prefer the explosive power delivery of a two-stroke over the consistent torque of a four-stroke. It is lighter than its four-stroke sibling, the 250 SX-F. In the Netherlands it frequently appears on the used market when owners move up a class or switch to four-stroke.

Before you buy
What to check before buying
- Check the top-end (piston and ring) for wear; two-stroke engines require rebuilds every 20-40 riding hours in competition use.
- Inspect the reed valve for cracks or damage; this is the most critical wear component of the two-stroke engine.
- Note the clutch condition; intensive use on sand or loam tracks wears clutch plates quickly.
- Check the frame and subframe welds for hairline cracks; motocross bikes are repeatedly subjected to heavy jump landings.
- Ask about race history and engine hours; a poorly kept logbook is a warning sign.
