Athena cylinder head gasket for Honda CBR125R motorcycles.

Athena carefully selects the material for each individual gasket to ensure the appropriate material is used, for example, exhaust gaskets are subjected to extreme heat and pressure so are made out of a material that can endure.
Athena have selected steel for their head gasket material, the metal remains strong under pressure and the conductive metal ensures heat is transferred equally between the cylinder and the head.

Athena equivalent to Honda 12251KGH900, 12251KTYD30
