Description
The Wiseco 520M04800 is a complete piston kit engineered for the Yamaha YZ80 to restore your engine’s compression and combustion efficiency after high-hour use or a top-end rebuild. Whether you’re prepping for race season or refreshing a worn motor, this OEM-spec replacement delivers the precision fit and durability that two-stroke dirt bikes demand, without compromising on performance or longevity.
Wiseco’s forged aluminum construction handles the thermal stress of aggressive riding while the 48.00 mm bore sizing ensures proper ring sealing and power delivery across the RPM band. This kit includes everything needed for a complete top-end refresh—piston, ring set, wrist pin, and circlips—so you can get back on the track or trail with confidence.
