ATHENA Exhaust Gasket for HONDA CR 125 1990-2004

On HONDA CR 125 from 1990 to 2004, the ATHENA S410210012045 exhaust gasket fits in place of the original part. At the junction between the engine and the exhaust, this gasket has to cope with very hot gases and vibration. Crushed or hardened, it lets gases escape: noise, spitting and loss of power.
