ATHENA Crankcase Gasket for YAMAHA DT 80 1986-1993

The ATHENA S410485008013 crankcase gasket is designed for YAMAHA DT 80 from 1986 to 1993. The crankcase gasket seals between two parts of the crankcase. It is replaced every time they are separated: refitting a crushed gasket means risking an oil leak and, on a two-stroke, an air leak that upsets the carburation.
