road legal

As the title says... feedback on driving technique, or pretty much anything else are very much appreciated.

Hey so i'm new here. I'm going to be picking up a new 2014 yz85 this week end. My intentions will be to convert it into a fully street legal supermoto. I was wondering what mods i would have to make. I'm thinking of putting 17" or 14" tires on it. preferably tires with some ridges. any...
