***** Fits 1981-2018 XR100/CRF100 *****

NEW! 120cc Big Bore Performance Kit (58mm):

- Aluminum cylinder with steel sleeve - High compression 58mm piston with rings, pin, & clips - Head gasket kit

Affordable and will make your XR100 or CRF100 a lot more fun to ride by adding some needed power. This kit does not require boring of the case - simply bolt on and go!!

There are no installation instructions, but if you can replace your piston, you can install this kit. If you don't have any experience working on your engine, we highly recommend the Clymer's repair manual available in this section. The parts are installed in the same manner as the stock Honda parts.
