You better check a little more about that. No state that i know of offers VIN NUMBERS for a frame that has none. I have been doing this for over 30 years and have MSO and registered for frame building and it is a hassle to get it done so i don't do it and the last MSO bike i did stayed at the State Police impound for a month and i had to have every paper that had a price on it for parts that went into bike. So i think someone is not giving you all the info and if you are in OHIO i know they don't because i sold a frame to a guy with numbers and we couldn't get it Titled and i had to do the ITS title to get it for him.
Dude if you can make a frame and get it titled for under $300.00 you would be rich because there is 100 guys on here that would buy it for that.
Check before you get burnt. Not trying to break your balls but i heard many stories on titles and i have bike builds all over the US and overseas and NEVER got a break on a title. DMV is the same in all states and they all bide by the same rules. 20 years ago yes you can get a RECON Plate NOT NOW. If you could i got 10 frames and would be in the truck heading that way.
