Refresh your 2-stroke top end with the VERTEX Cast Replica piston kit—OEM-style fit with modern durability upgrades. A moly-coated skirt and heat-treated cast alloy help speed break-in and extend piston life.
Bring back crisp compression and reliable performance with the VERTEX Top End Piston Kit (Cast Replica). Designed as an OEM-form replacement, this gravity-cast piston matches original fitment while adding proven material and surface treatments for long service life. It’s an ideal solution when your engine starts losing power, becomes harder to start, or it’s simply time for scheduled top-end maintenance.
The piston is heat-treated using a T-5 hardening and tempering cycle, and the skirt features a high-tech Molybdenum Disulphite coating to reduce friction. That means faster break-in, smoother operation, and improved wear resistance—especially important for high-revving 2-stroke engines.
