The Cylinder Works 10010-K02 Cylinder Kit is a complete standard-bore replacement kit designed for select Honda CRF450R and CRF450RX models. Featuring a 13.5:1 compression ratio and a matched Vertex piston, this kit helps restore top-end performance while supporting reliable service life and reduced engine noise. The cylinder is styled to closely resemble the original equipment component for a factory-style appearance.
This kit includes the cylinder, piston kit, and required gaskets for standard-bore applications. The cylinder features a nickel-silicon-carbide plating process intended to improve durability and extend service life. No machine work is needed for installation in compatible applications, helping simplify the replacement process. The top-end gasket kit does not include valve stem seals.
