Upgrade the top end of your ATV or motorcycle with the Cylinder Works 40001-K01 90.00 mm standard bore high-compression cylinder kit. Designed for select Kawasaki, Suzuki, and Arctic Cat applications, this complete kit includes the cylinder, matched piston kit, and required gaskets for a reliable replacement or performance-focused rebuild. The 11.3:1 compression ratio is engineered to support strong engine performance while maintaining practical fitment for the specified models.
The cylinder features a nickel silicon carbide plating process that promotes extended service life, improved durability, and consistent operation. Cylinder Works matches the cylinder with a Vertex piston to help provide dependable longevity, performance, and reduced engine noise.
