Restore top-end performance with the Cylinder Works Standard Bore Cylinder Kit, designed for select Kawasaki KX250F and KX250X models. This complete kit includes a standard-bore cylinder, matched Vertex piston kit, and the required top-end gaskets for a dependable replacement solution. The 78.00 mm bore and 14.1:1 compression ratio are engineered to support strong performance while maintaining a stock-style appearance.

The Cylinder Works cylinder is nickel silicon carbide plated for extended service life, improved durability, and consistent heat transfer. Its piston is matched to the cylinder to help promote longevity, performance, and reduced engine noise. The cylinder is styled like the original equipment component, making it an excellent choice for riders and technicians seeking a reliable replacement without an aftermarket appearance.

Installation requires no machine work when used for the intended standard-bore application. The top-end gasket kit does not include valve stem seals, so those components should be inspected and replaced separately as needed. Replacement pistons, gaskets, and ring sets are also available for future service. This kit fits the 2021 Kawasaki KX250X, 2021 Kawasaki KX250F, 2022 Kawasaki KX250F, and 2022 Kawasaki KX250X.
