ATHENA Engine Bearing for HONDA XL 500, XR 500 1978-1984

On HONDA XL 500, XR 500 from 1978 to 1984, the ATHENA MS350800210C3K engine bearing fits in place of the original part. In a motocross engine, the bearings spin fast and take hard knocks. Replacing a tired bearing at the right time saves the crankcase or the gearbox from damage.

4. Close up with new gaskets or a complete engine gasket kit.
