I don't know about useless, depending on what state you live in it can be fairly easy to plate a dirt bike. My 97 YZ250 supermoto is plated in KY and the bike has been since new. I know several guys who have plated CRF's, and YZ/WR's in both KY and OH.
One of those conversions might be a lot of fun.
