Description
The stock piston in your KTM 250 SX-F is a wear item—and when it starts to go, engine performance degrades fast. Wossner’s 80.95 mm piston kit restores full power delivery while improving durability and reducing friction losses, making it the ideal choice for racers and serious riders who demand reliability lap after lap.
This complete kit includes everything you need for a straightforward rebuild: the piston, compression rings, wrist pin, and retaining clips. The aerospace-grade aluminum construction combined with Wossner’s proprietary skirt coating ensures your engine runs cooler and quieter while handling the sustained high-RPM demands of modern 4-stroke competition.
