Rebuild your 2-stroke top end with a VERTEX Cast Replica piston kit made as an OE-style replacement with standard compression. Heat-treated construction and a molybdenum-disulphite skirt coating help speed break-in and extend piston life.
The VERTEX Top End Piston Kit (Cast Replica) is a complete, OE-style solution for refreshing worn 2-stroke top ends and restoring strong, consistent performance. Built from a gravity-cast aluminum alloy with high silicon content, it’s designed for reliable everyday durability while maintaining a standard compression ratio for predictable power delivery.
To reduce scuffing and shorten the break-in period, the piston skirt is coated with a high-tech molybdenum disulphite layer, while the piston is heat treated using a T-5 hardening and tempering cycle for improved strength and service life. With gaskets and essential small parts included, this kit streamlines your rebuild and helps get your bike back on track faster.
