Good To Know

Q: Is this an original Yamaha piston? A: No, this is a Wiseco piston kit made for Yamaha YZ80 applications, not an original equipment part. It serves as a replacement for the listed models.

Q: Does the cylinder need machining for a standard piston? A: A standard bore piston suits a cylinder still within original spec, so measure your bore before ordering. Confirm the cylinder is not worn beyond the standard size.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
