I am looking a buying 03 or later WR450. I am sure you guys get asked this all the time, but I couldn't see a post asking about a California green sticker. Is the 03/04 bike green sticker? Also, can you also (if you put on all the necessary equipment) register the bike for "on-highway" use in California? I would like to do some dual-sport events. I am considering buying a used WR in Nevada. Do you know of any issues of bringing it to California? Thanks so much.
