Specs At A Glance

Good To Know

Q: Do these rings need to be gapped before installation? A: They are pre-gapped for a standard fit, but we recommend checking ring end gaps with a feeler gauge to verify they fall within factory specifications for your specific cylinder bore.

Q: Are these rings compatible with OEM Yamaha pistons? A: They are designed to work with .020 over bore pistons from various aftermarket suppliers and should not be used with standard bore pistons.

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