I made my CT 90 Off Road Legal in the State of Oregon. Took an Off Road Vehicle Safety test via internet and got my card (no charge). At my age I wouldn't have had to do this till Jan 1st 2014, but its now out of the way and I paid $10.50 for a two year Off Road Tag (license) that must be attached to the bike when riden on any State, Federal, or property not owned by the rider. I don't think there is anything left? I hope!
