wouldn't it just be surface rust on the chain?. I know you can't stop the rust on my car, but for some reason I figured I'd just take a brush to my chain and it would come off. I don't think the rust on my chain is going to eat away my chain like it does in the wheel
Hydrated iron oxide is permeable to air and water, allowing the metal to continue to corrode - internally - even after a surface layer of rust has formed. Given sufficient hydration, the iron mass can eventually convert entirely to rust and disintegrate.
Corrosion of aluminium is different from steel or iron, in that aluminium oxide formed on the surface of aluminium metal forms a protective, corrosion resistant coating, a process known as passivation. wells of my car..
so I can't find if motorcycle chains are made out of steal or aluminum. I just noticed a little rust on the outside of my chain, not to say the inside near the o-rings arn't rusted.
