VERTEX Cast Piston – Ref. 22712A
Designed for off-road competition, this VERTEX cast piston is aimed at motocross riders equipped with a KX125 (KX125L) from model years 2000 to 2002. Made from aluminum, it adheres to original profile and tolerances with a finish suited to the demands of motocross: lightweight, good thermal conductivity, and wear resistance inherent to high RPMs.
This oversize A piston is designed for a 54.00 mm bore and provides a piston-wall clearance that complies with factory specifications. It directly replaces the original piston; however, be sure to check and, if necessary, replace rings, pin, and clips during reassembly. For a secure installation, follow the manufacturer's recommendations regarding clearance and break-in procedure.
