Vertex Pro Replica Forged Piston Kit for 250cc 4-Stroke

Elevate your motorcycle's engine performance and durability with the Vertex Pro Replica Forged Piston Kit. Engineered as a direct OE replacement, this kit delivers superior strength and longevity for your 250cc 4-stroke machine, ensuring reliable power output and a refreshed top-end.

Description

Designed for demanding conditions, this Vertex Forged Piston Kit is an essential upgrade for any 250cc 4-stroke engine. Each piston is meticulously forged from high-strength 2618 aluminum, providing exceptional durability and resistance to the stresses of high-performance riding. The advanced T-5 hardening and tempering cycle further enhances the piston's structural integrity and heat resistance, ensuring consistent performance even under extreme operating temperatures. To promote faster break-in and significantly extend piston life, the skirt is coated with a high-tech Molybdenum Disulphite (Moly) coating, reducing friction and wear. With a precise 79.00 mm bore size and an aggressive 13.9:1 compression ratio, this piston is engineered to optimize power delivery. As an OE replica, it guarantees perfect fitment and function, making it an ideal choice for a complete engine refresh. The kit includes the piston, Nitride Coated Steel rings, wrist pin, and circlips, providing all necessary components for a comprehensive top-end rebuild.
