Restore top-end performance with the Cylinder Works 40001-K02 Standard Bore Cylinder Kit. Designed for select Kawasaki KFX 400 and Suzuki LT-Z400 QuadSport Z applications, this complete kit includes the cylinder, piston kit, and gaskets needed for a reliable replacement or engine rebuild. The standard-bore configuration preserves the original engine bore while providing a matched piston and cylinder combination for consistent performance.
The cylinder features a nickel silicon carbide plating that promotes extended service life, durability, and effective heat management. Cylinder Works matches the cylinder with a Vertex piston to support longevity, performance, and reduced engine noise. The cylinder maintains a stock-like appearance and is engineered for installation without additional machine work when used as specified. The included top-end gasket kit does not include valve stem seals.
Fitment: This kit fits 2003-2006 Kawasaki KFX 400 models and 2003-2008 Suzuki LT-Z400 QuadSport Z models. It is intended for standard-bore applications and provides an 11.3:1 compression ratio.
