A motorcycle bill of sale can be used to get a title for a motorcycle once a transaction has been completed. This document is mandatory in many states to transfer the title of the vehicle with the local DMV or motor vehicle authorities. It may also be essential if the original ownership papers have been lost.
To use the bill of sale to transfer the title of a motorcycle, the new owner must visit their nearest DMV with the vehicle and the bill of sale. A VIN inspection will need to be done and if that passes without any issues (such as the vehicle being reported stolen or a lien existing against it) you will then be given the necessary forms to transfer the title.
All that you then need to do is complete the title transfer documents, pay a fee and then wait a few weeks (the DMV will normally give you temporary registration to use the bike in the meantime). You will then be mailed the new title once it has been processed and will then the vehicle will be fully registered in your name.
