VERTEX Cast Replica piston kit for 2-stroke engines—ideal for a reliable OE-style top-end refresh with fast break-in and long service life. Cast aluminum alloy construction with advanced skirt coating helps reduce friction and wear.
This VERTEX Cast Replica Piston Kit is built for riders who want an OE-style replacement that restores compression and performance without compromising reliability. It’s a smart choice for a routine 2-stroke top-end service, helping your engine run cleanly and consistently while reducing downtime.
The piston is made from a gravity-cast aluminum alloy (not forged) with 18% silicon content for durability and stable operation. A high-tech molybdenum disulphite skirt coating helps reduce friction for faster break-in and improved piston life, while the T-5 hardening and tempering cycle supports long-term wear resistance under demanding riding conditions.
