Kawasaki KX 85 Piston Kit - Vertex Pistons - Top End - `01-`13. A precision top-end kit designed for KX85 models from 2001 through 2013, delivering an exact-fit replacement piston set ready for installation.

This Vertex piston kit includes everything required for a proper top-end service: piston, rings, wrist pin and circlips. Available in A, B or C fitments to match your cylinder bore, the pistons help maximize power and performance while reducing blow-by and oil consumption when matched correctly. Skirts receive a molybdenum disulphide (MoS2) coating to promote faster break-in and longer piston life. Each piston is heat treated using a T-5 hardening and tempering cycle for consistent strength and durability.
