According to Wikipedia, they were: The Kz1000P (police) sits on 18 inch wheels with Dunlop run-flat tires. The front tire is size MN90-18, and the back tire is size MR90-18. They came in either a cast magnesium or chrome-plated wire spoke rims. en.wikipedia.org/wiki/Kz1000

See the discussions above. The general production wheels may have been called 'mags' but they aren't composed of magnesium or even magnesium alloy...it is aluminum alloy.

Are you saying they made magnesium wheels for street use?
Just to clarify, both Mcdroid and I know that the stock aluminum wheels are called mags because they look like the race mag wheels, that's been going on for at least 50 years.
And we both know that magnesium wheels were used on race bikes (aren't they using some kind of composite now?), and that they are a real bad idea on the street. A member here had them on his street bike and broke the front one (Kraz1 maybe?).
I remember when I was a kid someone saying that the 63 Corvette had optional real magnesium wheels, and there was such a problem with breakage the Feds banned them from street use. Don't know if any of that is actually true though.
After an hour or so of searching I still don't know much more than when I started. Found a lot of posts claiming there are no DOT approved magnesium wheels, and a bunch of ads claiming a company named OZ makes and sells the only DOT approved magnesium wheel for motorcycles.
I give up, I'm just going to stay confused :silly:

Just restating the root of the misconception of "mag" wheels, I don't believe it was said before in this thread.
You are correct, OZ Racing (a strong partner of Sanctuary I just found out) makes true magnesium wheels. Also, Marchesini makes true magnesium wheels as well. Those are the only two manufacturers that I'm aware of. They are very brittle, but hey, if they're making carbon fiber wheels... Ever see one of those magnesium fire starters? Just imagine one of those wheels failing then bursting into 4000 degree flames!!!

Mag is not brittle and does not start on fire readily... Thin sections when exposed to flame will catch on fire, but items such as wheel rims or other heavy wall items (greater than 2mm wall stock) can have a welders torch on them for a long time before they catch. Mag dust however is very dangerous...
The biggest problem with mag is corrosion... it corrodes way faster than aluminum when left in a bare state... it is usually anodized or painted after casting.
The Kawasaki stuff from years ago was all aluminum - cast mag has all the good properties of aluminum but is lighter in weight, that's why they use it for race rims.
