Good To Know

Q: Do I need to machine my cylinders to fit these pistons? A: Yes, these are overbore pistons requiring the cylinders to be bored and honed to the specified 65.5mm size by a qualified machine shop.

Q: Are wrist pin bearings included? A: The kits include wrist pins and circlips, but wrist pin bearings are sold separately for Yamaha Banshee applications.

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