VERTEX Cast Piston — Manufacturer Reference: 22500C
VERTEX aluminum piston, designed for motocross use. Made in a cast version, it fits cylinders that have been bored to 47.00 mm (oversize letter C). The profile and dimensions comply with the "piston compression: standard" configuration, to replace an original piston during an engine overhaul.
This piston is suitable for engine restorations after boring and fits into the standard rod/pin/ring assemblies designed for the C size. It is particularly suitable for the YZ 80 models listed below and other machines with the same bore and specifications.
Before installation, check compatibility with your cylinder (bore, piston-cylinder clearance, compression height) and replace rings and pin if necessary to ensure reliable motocross performance.
