Upgrade the top end of your motorcycle with the Cylinder Works CW50009K03 95 mm Standard Bore High-Compression Cylinder Kit. Designed for select KTM and Husqvarna 450 models, this complete kit includes a cylinder, matched piston kit, and gaskets for a straightforward replacement using standard-bore specifications. The 13.1:1 compression ratio supports strong performance while maintaining the stock-style appearance of the original cylinder.
The cylinder features a nickel silicon carbide plated bore for extended service life, consistent performance, and improved durability. Cylinder Works matches the cylinder with a Vertex piston to help promote longevity, responsive engine operation, and reduced engine noise. No machine work is needed for installation when used with compatible applications and properly serviced engine components.
This kit fits the 2022 KTM 450 SX-F Factory Edition, 2023 KTM 450 SX-F, and 2023 KTM 450 XC-F. It is intended as a standard-bore replacement and includes the components needed for a complete top-end rebuild. The top-end gasket kit does not include valve stem seals. Replacement pistons, gaskets, and ring sets are available separately for future maintenance. Always verify model year, engine configuration, and installation requirements before ordering.
