VERTEX Cast Piston reference 23249A, designed for the maintenance and restoration of 250 cm3 engines. Aluminum cast piston offered in standard compression configuration to maintain the original character of the engine.
This piston is aimed at riders and mechanics looking for a reliable replacement part to keep the original distribution and displacement. Its finish and tolerances are suitable for both motocross and roadster applications, for engine overhaul work or after cylinder reconditioning. The oversize "A" indicates a size suitable for re-machined bores — check engine dimensions before installation.
