Restore reliable compression and smooth power delivery with the VERTEX Forged Replica Piston Kit for 4-stroke engines. This is a forged OE-replacement style piston designed to match OEM fit and function, while adding the benefits of premium forging and surface treatments for long service life.
If your bike is getting harder to start, losing power, or showing signs of top-end wear, a quality piston kit is one of the most effective ways to bring the engine back to spec. The piston is heat-treated using a T-5 hardening and tempering cycle, and the skirt features a molybdenum disulphite coating to reduce friction—helping the engine bed in faster and extending piston life under demanding riding conditions.
Key features:
✅ T-5 heat-treated piston for strength and durability
