VERTEX Cast Replica Piston Kit in OE form for reliable 2-stroke top-end rebuilds. Heat-treated and finished with a moly-coated skirt for faster break-in and longer piston life.
Restore like-new performance with an OE-style piston kit. The VERTEX Cast Replica Piston Kit is made in the original OE form, making it an excellent choice when you want dependable fitment and consistent performance for your 2-stroke top-end rebuild. Every piston is heat treated using a T-5 hardening and tempering cycle, while the skirt features a high-tech molybdenum disulphite (moly) coating to reduce friction, speed up break-in and help extend service life.
This kit uses a gravity-cast aluminum alloy (not forged) with 18% silicone content—designed to be extremely light yet strong. Replica pistons and rings are intended as OEM replacements, ideal for riders who want a quality refresh without changing compression or engine character.
