    People constantly get try to interchange inches with millimeters, and it doesnt work! The top of the piston should be marked. The size will be designated in mm. Also a quick check of the decimal point will tell you as well. Inches are designated in thousandths (.020) and go in increments of .010". (.010", .020", .030" etc.) Millimeters are in tenths, and go in increments of .25mm. (.25mm, .50mm. .75mm, 1.00mm etc.) .010" = .25mm. If yours was bored .020, that would be in inches, and you would need a .50mm oversize piston. If you have a Honda Piston, you will have to get Honda rings, and you will have to go through a Honda OEM parts dealer, such as Service Honda.

    Actually you can use Sudco or Pro-X rings with a Honda Piston. I do it all the time.
