All VN750s sold in the U.S. have the VIN stamped into the steering head. You cannot title it as a VN750 unless it has a VN750 steering head. You can get a VN750 frame with a title, and build the steering head into the frame. In most states, in order to title a custom built vehicle, it not only has to be inspected by the motor vehicle division to see if it is roadworthy, but you have to have a receipt for every single part on it. Kind of difficult if you already have the parts and no receipt. What you want to do would not be possible in my state. Some custom built frames come with a VIN and a title. That makes it easy to register it as whatever the description on the frame says. It will need a year and model number/name. and even then it can be difficult to insure if that information does not show up on the insurance companies list. I won't touch a bike without a title. They make it almost impossible to prevent people from registering stolen vehicles.
