Is my OHV registration valid in other states?

Do I need insurance for my dirt bike in Colorado?
For off-road use, insurance is not mandated by the state, though it is highly recommended to protect against damage or liability. However, if you successfully convert your dirt bike to be street-legal, you are required to carry the same level of liability insurance as any other motorcycle or passenger vehicle on the road.
