Kawasaki KX 250 F Piston Kit - Vertex Pistons - Forged Replica - `11-`14. A direct-fit forged replica piston kit designed for 2011–2014 KX250F models, providing the components needed for a reliable rebuild or performance refresh.

This Vertex piston kit is engineered to match cylinder bores with Exact fit A, B or C options to minimize blow-by and reduce oil consumption while maintaining intended compression and performance. Each kit includes the piston, rings, wrist pin and circlips required for installation. Skirts are finished with a molybdenum disulphide (MoS2) coating for quicker break-in and improved skirt wear. Pistons are heat treated using a T-5 hardening and tempering cycle to ensure consistent material properties appropriate for a forged replica application.
