VERTEX Pro Version Forged Piston — Manufacturer reference: 22643A
Designed for reconditioned cross cylinders, this VERTEX Pro Version piston is forged from aluminum to provide superior mechanical strength compared to a cast piston. It is aimed at riders and mechanics looking for a reliable replacement part during an engine overhaul or reboring.
The oversize letter A indicates that this piston is designed for a +A machined bore, facilitating installation after reboring. Its dimensional tolerances are suitable for common interventions on 125 cc cross engines, and it is particularly well-suited for the models listed below.
A replacement part intended for maintenance work, this VERTEX piston fits into an engine rebuild where manufacturing quality and dimensional stability are essential for restoring clean and durable operation of the moving assembly.
