ATHENA Cylinder Head Gasket for KAWASAKI KDX 80, KX 80 1981-1988

On KAWASAKI KDX 80, KX 80 from 1981 to 1988, the ATHENA S410250001088 head gasket fits in place of the original part. Between the cylinder head and the cylinder, the head gasket contains the pressure of every explosion. Once tightened, it takes the shape of the parts: on reassembly you need a new gasket to keep full compression.
