The Cylinder Works CW50009K02 Cylinder Kit is a complete standard bore top-end solution for select KTM 450 EXC-F and Husqvarna FE 450 motorcycles. Designed for a 95 mm standard bore and 11.8:1 compression ratio, this kit includes the cylinder, matched piston kit, and required gaskets for a reliable engine rebuild or replacement. The cylinder maintains a stock-like appearance while delivering the durability and performance expected from Cylinder Works components.
Each kit is matched with a Vertex piston to promote long service life, consistent performance, and reduced engine noise. The cylinder features a nickel silicon carbide plating process that improves wear resistance and helps extend component life. No machining is required for installation when used with the appropriate standard-bore application, simplifying the top-end replacement process. The included top-end gasket kit does not include valve stem seals, so those seals should be replaced separately as needed.
Fitment includes 2017-2021 KTM 450 EXC-F models, including the 2018 KTM 450 EXC-F Six Days, and 2018-2021 Husqvarna FE 450 models. Cylinder Works manufacturer part number CW50009K02 and vendor part number 422-50009K2 identify this complete replacement kit. Replacement pistons, gasket sets, and ring sets are available separately for future service requirements.
