Specs At A Glance

Good To Know

Q: Does the cylinder need to be bored to use this oversize piston kit? A: Yes, this piston requires the cylinder to be bored and honed to 68.50 mm so the piston to wall clearance is correct. Fitting an oversize piston into a standard bore will not work.

Q: Is this kit complete for a top end rebuild? A: The kit supplies the piston, rings, wrist pin, and clips, while gaskets and bearings are generally sold separately. Check the rest of the top end parts before assembly begins.

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