  • Engine parts: Metal question

    What metal/alloy are the engine cases, cylinder and head cast out of? Side & valve covers?

    Thanks in advance!
    Easy on the throttle, steady on the gears, roll her over gently and she'll last for many years.

    I believe they are all an aluminum alloy.

        This article is about car engines but probably similar alloys used in motorbike engines
