Honda CRF 450 R Forged Replica Piston Kit - Vertex Pistons - `19-`24 is a direct-fit replacement piston kit designed for 2019–2024 CRF450R models. This kit provides the components needed to refresh or upgrade the top end with precision machined, forged replica pistons built to Vertex standards.

Designed as an exact fit in A, B, or C sizes to match your cylinder bore, each kit includes the piston, rings, wrist pin and circlips required for installation. Skirts receive a molybdenum disulphide (MoS2) coating for quicker break-in and improved skirt life. The pistons undergo a T-5 heat treatment hardening and tempering cycle for consistent material properties. Using the correct match reduces blow-by and helps control oil consumption without adding unverified performance promises — making this a solid choice for riders planning rebuilt or modified top ends who want a dependable, factory-compatible replacement.
