PISTON KIT 90-01 ZX11 KAW, WOSSNER K8801D100-4 ROAD, KAWASAKI
Wossner piston kit with a 77mm bore is a standard replacement for the Kawasaki Z11 (ZX11) models. Forged in Germany for high durability and optimal performance, it is engineered for efficient heat transfer and consistent expansion behaviour under thermal stress. The elliptical piston design distributes pressure evenly, helping to prevent piston collapse during high-load operation. Features include forged construction for enhanced strength and thermal resilience, optimised for efficient combustion chamber heat dissipation, and an elliptical design that provides a consistent bearing surface under heat expansion. It offers even thrust load distribution that minimises localised stress. Manufactured in Germany. Specifications: Bore: 77mm (Standard), Actual bore: 76.95mm, Display volume: 1080 / 1109 cm³, Stroke: 58.00mm, Clearance: 0.06mm, Wossner compression ratio: OEM, OEM compression ratio: 11.00:1, Dome volume: -3.70 cm³, Compression height: 25.00mm, Theoretical weight: 209.00g, Lock Part Number: CW18, Pin Part Number: WP031, Ring Set Part Number: 770XDS.
