VERTEX Cast Piston – Manufacturer Ref. 22387A

Replacement piston designed for high-performance motocross engines, intended for Honda CR 250 R (ME03) models from 1994 to 1996. Cast aluminum piston manufactured according to VERTEX standards for precise engine assembly during a re-bore or complete overhaul.

This piston is suitable for motocross engine preparations where the bore size corresponds to oversize A. It is integrated into restoration operations to achieve correct piston-cylinder clearances and ensure reliable operation of the top-end. Its aluminum construction provides a balance between inertia and thermal resistance, suitable for the demands of off-road practices.

Before installation, check compatibility with your engine (reference and year) and follow installation procedures: checking clearances, installing appropriate rings, and timing moving parts. Sold as a spare part: suitable for refurbishment or replacement during a re-bore.
