Honda CRF450X Side Cover Gasket Kit - Vertex Pistons - High-performance MicroPore material - '05-'17. This gasket kit replaces the inner clutch/side cover gaskets for Honda CRF450X models from 2005 through 2017, offering an OE-spec fit with high-performance material where applicable.

Manufactured by Vertex, these side cover clutch gaskets are precision-cut from factory-grade materials to match OE specifications.

The kit is intended for enthusiasts who need accurate fitment for maintenance, rebuilds, or custom installations without altering engine components.
