Good To Know

Q: Is this piston kit for a CRF250R or CRF250X? A: This kit is specifically designed for the CRF250R model; the CRF250X uses a different piston and should not be substituted.

Q: Can I use this piston in a cylinder that has been oversized? A: No, this is a standard bore piston meant for stock cylinder dimensions; if your cylinder has been bored oversize, you need an appropriate oversize piston kit.

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