Description
The stock piston in your YZ125 can’t handle the demands of aggressive riding—wear accelerates, blow-by increases, and power delivery suffers. This Wössner 8091DB kit restores your engine to peak performance with OEM-quality components engineered to withstand the heat and stress of 2-stroke racing. Install it and get back the crisp throttle response and reliability your bike deserves.
This complete kit includes everything you need for a straightforward top-end rebuild: piston, compression rings, wrist pin, and circlips. No hunting for matching components or dealing with incomplete solutions—just bolt-on simplicity that gets your YZ back on the track.
