Good To Know

Q: What does the 54.50mm figure mean on this ring set? A: It is the bore diameter the rings are sized to fit, so the piston and cylinder must match that measurement. Confirm your bore before ordering.

Q: Can I install new rings without checking the cylinder? A: Ring seal depends on cylinder condition, so measuring bore wear and checking end gap first is the safe approach. Worn or out-of-round cylinders may need service before rings will seat.

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