Just about to street legal my 01 kx500 in Flagstaff, AZ. No inspections here. What you have to have though is headlight, tail light, brake light, horn, and mirror. My main concern is being hassled by the cops for the noise. I just want to be able to ride the 1 mile from my house to get to the woods. Also, there is something very cool about riding a bike as crazy as the 500 LEGALLY on the street.
