I run the rear wm-3 rims off of older dirt bikes on my race bike. The front is off of an 80s vintage RM125 it is anodized gold and my front is off a cr125. I found them both on e-bay for under $25 each. I cut the spokes with a bolt cutter and threw away the hubs cause they were both junk. That is why I got them so cheap. Don't worry about the rim locks. They are just bolt in rubber clamps that hold a dirtbike tire from slipping on the rim. They just leave a hole in the rim that looks like a valve stem hole. Either leave it or fit a rubber plug in it.
