Good To Know

Q: Does this piston need any machine work on the cylinder? A: It is a standard bore size, so it fits a cylinder that has not been overbored. Confirm your bore measurement before ordering.

Q: Should I replace rings and clips at the same time? A: Yes, a top-end job is the right time to install fresh rings, pin, and clips for a complete seal. Check that they match the 96mm bore.

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