VERTEX cast piston designed for original and replacement mounts on small displacement 125cc engines. Offered in machined aluminum with oversize tolerance, this piston is intended for engines equipped with an enlarged bore and requires adherence to piston/cylinder clearances for reliable operation.
Designed to restore the sealing and original geometry on compatible 125cc engines, this piston is suitable for common applications on MTX/NSR125. It is particularly well-suited for top-end rebuild operations: replacement after cylinder reboring or due to advanced piston wear.
Main compatibilities:
Before installation, verify the manufacturer's specifications and check the piston/cylinder clearance, ring alignment, and condition of the pin. Product delivered without rings or pin, refer to the necessary parts for a complete top-end refurbishment.
