Kawasaki KX250F Forged Replica Piston Kit - Vertex Pistons (2021–2022). A complete, direct-fit piston kit engineered for the KX250F model years 2021 and 2022 that replaces worn pistons with a forged replica designed for correct fit and reliable service.

This Vertex kit is made to match A, B or C cylinder bore sizes and includes the piston, rings, wrist pin and circlips required for installation. Pistons are heat treated using a T-5 hardening and tempering cycle for consistent material strength. Skirts are coated with molybdenum disulfide (MoS2) to promote a faster, controlled break-in and to reduce wear over time. By providing correct clearances for the KX250F platform, the kit helps reduce blow-by and oil consumption when installed to the appropriate bore specification. We recommend verifying bore size prior to purchase and professional installation if you're unsure.
