I know this isn't going to help your question about registering the Ural in NJ, but I did have a little problem in New York State and purchased from a NY dealer. The dealer only had the inspection done and left the registration to me. He delivered it to my home and the following day I drove to the DMV. When they entered the VIN number into their computer it didn't match anything. I explained it was a brand new 2007 Ural (this was done in 2007). She said they would accept the paperwork when the inspection was done.. I never received any paperwork from the inspection, just the sticker attached to the frame. She then said if I could get a picture of the VIN on the frame. That's almost impossible since it's on the hack side and if I remember the painting was done after the numbers were put on. So I took a paper and rubbed a pencil over the top to get a trace. I took that back. She studied it like she was looking for fake currency and questioned one of the letters. Apparently she had a change of heart when she looked at my VERY disturbed expression on my face. She said she'd force the paperwork through and I got my registration and title....Whew!!!
