Here in the US it is possible to make an mx bike street legal and get a license plate. I think some states won't let you but most will. Most states require an inspection of the vehicle once its brought up to street legal. I'm in Montana so all we have to do is fill out a form and check off each category and sign that the vehicle meets all street legal criteria and a plate can be obtained. For off road use a trail sticker is also required. The requirements are: horn, headlight, tail and breaklight, license plate light, mirror, dot approved for road use tires, and a couple of reflectors. Turn signals are nice but you can get by with hand signals if u want. The wr is easier to make street legal but it still is not even close from the factory. The fi yz's can run the headlight off the efi if u use a low draw led and the horn and other accessories can b run off an external battery u add and recharge before rides. Making a carbed yz street legal would b more of a pain, but is doable. I got the wr for the electrical but the wide ratio tranny is not my favorite for snow.
