2003 KX 250: What's the deal with those rims?

What's the deal with the rims on the 2003 KX 250? They are like none I've ever seen before. They're not the same standard stock wheels we're used to seeing. And they're not Excels.

As a matter of fact, they look totally different. Most rims have a flat edge on either side (right where the rim meets the bead of the tire). However, this rim is totally round from one side to the other. No flat edges...no lips...very strange.

And the coating is weird too. They're not a polished aluminum like the usual stockers or Excels. And they're not anodized. It's more like they're painted or have some other type of coating.

What gives?

Cool. Well, they look like a pretty rugged rim. I've never seen them before. I just wonder how durable that paint or coating is. I have a feeling that stuff would be all hacked up before too long.
