Good To Know

Q: Is this a standard or oversize piston? A: This is a standard bore piston, so it pairs with a stock-size cylinder rather than a bored-over one. Measure your cylinder before ordering to confirm it is still at standard size.

Q: What else should I replace during a top-end job? A: Along with the piston, plan on fresh rings, a wrist pin, and a circlip set, and inspect the cylinder and plating. Replacing those together helps the new piston seat and seal properly.

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