Honda CRF 250 R Piston Kit - Vertex Pistons - Top-End - `04-`07. This Vertex top-end piston kit is designed for 2004–2007 CRF250R models and provides the components needed for a proper top-end rebuild with factory-style fitment.

Designed for riders who demand accurate, reliable replacement parts, the kit includes piston, rings, wrist pin and circlips. Exact-fit A, B or C pistons match your cylinder bore to help reduce blow-by and oil consumption while preserving combustion efficiency. Skirts are coated with molybdenum disulfide (MoS2) to promote quicker break-in and lower initial friction. Pistons are heat treated using a T-5 hardening and tempering cycle for consistent durability under racing and trail conditions.
