Vertex Top End Piston Kit (Forged Replica) is a forged OE-form replacement for rebuilding your 250cc 4-stroke top end with strength, durability and fast break-in. The moly-coated skirt helps reduce friction and extend piston life.
Vertex Top End Piston Kit (Forged Replica) is designed for riders who want a dependable, OE-form top-end rebuild with the added confidence of a forged piston. Built from strong 2618 aluminum and heat-treated using a T-5 hardening/tempering cycle, it’s made to handle demanding riding while maintaining consistent performance. The high-tech molybdenum disulphite (moly) skirt coating reduces friction for a faster break-in and helps increase piston service life.
This kit simplifies your rebuild by bundling the critical components you need in one package—helping you restore compression, reduce blow-by and get your engine running cleanly again without chasing individual parts.
