Pretty sure a magnet won't stick to either. Doesn't magnesium burn really hot white? Could try lighting them on fire lol

no a magnet wont stick to either. but if you have a bare spot that wont be seen (like under the inside of the tire) scratch the surface with a file to remove any oxidation and pour some vinegar on it if its magnesium it will bubble alot if it doesnt do anything its aluminum

Or, like someone said, Magnesium will start on fire.

They <u>never</u> made the Motomag II's in magnesium. And don deface any part of them if you expect to try and sell them.

That much aluminum isnt gonna be light. Compare that to the Skyway mags on my bike. Night and day difference.
