Product Description

The Vertex Forged Replica Piston Kit 22951A delivers exact OE replacement performance and reliability for your 4-stroke off-road motorcycle. Engineered with a precision 89.96 mm piston diameter for a 90.00 mm cylinder, this kit restores factory compression and throttle response across demanding trail and track conditions.

Manufactured using advanced forging technology from high-grade 2618 aluminum alloy, each piston undergoes a T-5 hardening and tempering cycle for superior structural integrity under high RPM loads. The piston skirt is finished with an advanced Molybdenum Disulphite coating to ensure a fast break-in period and reduced friction, maximizing long-term durability.
