ATHENA Cylinder Head Gasket for YAMAHA DT 80, TY 80 1974-1984

The ATHENA S410485001087 head gasket is designed for YAMAHA DT 80, TY 80 from 1974 to 1984. The head gasket seals between the cylinder head and the cylinder: it holds in the combustion pressure and, depending on the engine, the coolant. Crushed when tightened, it can never be reused.
