The VERTEX Forged Replica Piston Kit is designed as a forged OE-style replacement for riders who want dependable durability without changing the original engine character. Made from 2618 forged aluminum, it delivers excellent strength under high load and temperature—ideal for demanding motocross and enduro use.
If your top end is showing wear (loss of compression, increased oil consumption, reduced throttle response), this kit helps restore crisp performance and reliability. The piston is T-5 heat treated for stability, and the molybdenum disulphide skirt coating supports a faster break-in while helping reduce friction and extending piston life.
Key features:
✅ Forged OE-form replica piston for original-style fit and function
✅ T-5 hardening/tempering heat-treatment process for durability
✅ Moly-coated skirt for reduced wear and quicker break-in
Benefits of use:
🔹 Strong forged construction compared with many cast alternatives
🔹 Helps bring back consistent compression and smooth engine operation
🔹 Complete kit reduces downtime—everything needed for installation in one pack
