ATHENA outer Clutch Cover Gasket for YAMAHA YZ 125 and FANTIC XE 125, XX 125 2005-2026

On FANTIC XE 125, XX 125 and YAMAHA YZ 125 from 2005 to 2026, the ATHENA S410485008100 clutch cover gasket fits in place of the original part. On the clutch side, the cover holds in the gearbox oil. Its gasket crushes when tightened: refitting the old one means risking an oil leak onto your boot or into the engine.
