CR 250 1997-2001 TOP END KIT SINGLE RING RACE PISTON
Vertex two-stroke top-end kits bring together the principal service parts required for a piston replacement in one application-specific package. The piston is designed for controlled thermal expansion and dependable bore clearance, with a molybdenum-disulphide skirt coating to support running-in and reduce friction.
Each kit includes the complete piston assembly with rings, wrist pin and circlips, together with the matching top-end gasket set and wrist-pin bearing for the stated motorcycle application. Select the correct piston size for the measured cylinder bore and confirm the model and year range before installation.
