Honestly you can just license anything you want. I took the title to my 1984 XR500R to the DMV and got plates on it. There is nothing street legal about it, it even says offroad use only on the frame, it doesnt even have a brake light. There were no probs at all getting a plate for it. I asked for one and they handed it to me. They didn't ask what it was and didn't ask to see it. I garantee you could just take an ATC250R title to the DMV and ask for a plate and you'd get it. Just because you can get a plate on something doesn't make it legal.
