I got my KLX300 street legal pretty easily. What you need in AZ is a headlight, a horn, a brake light, a mirror and a licence plate light. I put a bicycle bell as my horn. The horn has to be able to be heard 200 feet away. I put a hydraulic brake switch in my rear master cylinder and change the bub holder in the tail light to a tail light/brake light combo. I live in Tucson and did not have to smog the bike, All I had to do it go the the MVD and fill out a form stating that I had complied to all the rules to get it street legal. I also had to show proof of insurance. I have never been stopped by a cop they see a lot of street legal bike and quads around here. My Raptor is street legal too.
