Complete Piston Kit to rebuild the top end of a Honda 100. This is a oversize piston kit - we have sold out of the standard bore kits. We only have a limited number of these pistons remaining. Kit comes complete with rings set, piston pin, circlips and a piston. Very few oversize kits are still available. This kit will not fit the 1976-1978 XL100.
Have your cylinder measured by a professional! This is not a big bore kit. To install this you will likely require a bore and hone of your cylinder.
Fits models with 14mm wrist pin:
1970-1973 CL100 | CL100S
