I bought a bike back in 2010 that did not have tags. I had bought on a bill of sale to find out that wasn't good enough. SO, thanks to the DMV, they stated to me that the bike was not stolen and the last time it was registered was in 2002. In MN, if a bike hasn't been registered in 7 yrs, they purge the registration/title information from their records. Which, in this case, that info was sitting in the purge file waiting to be purged. Because the DMV would not release to me the name of the last owner the bike was registered to, my buddy used the VIN and looked up the info. Which then using that info, we applied for a duplicate title. When it was mailed in, it was returned stating that the bike was not in the system. (great way to test if it was purged or not). Once this was discovered, I went to the DMV to inquire how I can get a title for it and I was told this: Take pictures of the bike, one of each side, the front, the back and to include pictures of the VIN and engine #. Apply for a title, submit registration fees. When I did all this, I received new plates with current tabs and a title a month later. Oh, and the pictures had to show that the bike was actually a bike. Meaning at minimum a rolling chassis/frame. It was pretty simple once I found out the original title/registration was non existent. So, check with the DMV. At least in CO, you'll walk away with a title in hand the day you submit your forms. And just to be on the safe side, check in with the local PD and have the VIN # ran just to make sure it's not HOT.
