Kawasaki ZX600 Piston Kit - Wiseco - 13.8:1 CR 2638XA, 67.00 mm Bore - `07-`18. This Wiseco Forged Series piston kit is built for riders looking to refresh or upgrade the top end on ZX600 engines from 2007–2018.

The kit contains a forged piston engineered for strength and longevity, along with the necessary installation hardware. Forged construction helps the piston resist deformation and fatigue under high stress, making it suitable for performance-focused street or track applications where durability matters. The 13.8:1 compression ratio and 67.00 mm bore match the specified build for the ZX600, and the package includes wrist pin, rings, and circlips so you have a complete set ready for installation.
