Upgrade the top end of your Honda motocross or cross-country motorcycle with the Cylinder Works 10010-K02HC High-Compression Cylinder Kit. Designed for a standard-bore application, this complete kit includes the cylinder, matched piston kit, and required gaskets for a focused engine refresh. The 14.4:1 compression ratio is engineered to support strong performance while maintaining the fit and appearance of the original equipment cylinder.
The cylinder features a nickel silicon carbide plating process that promotes extended service life, dependable heat management, and consistent bore performance. Cylinder Works matches the cylinder with a Vertex piston to help promote durability, reduce engine noise, and deliver reliable operation. The stock-style appearance integrates cleanly with the engine, and no machine work is required for installation when used with the applicable standard-bore engine configuration.
This kit fits the 2019 and 2020 Honda CRF450R, 2019 and 2020 Honda CRF450RX, and the 2019 and 2020 Honda CRF450R Works Edition. It is intended for compatible standard-bore applications and includes the components needed for a complete top-end replacement. The top-end gasket kit does not include valve stem seals. Replacement pistons, gasket sets, and ring sets are available separately for future service needs.
