I was told by one the the representatives there, that i should fill it out twice, that way they dont have to leave their desk to photocopy it. The application is the registration. They just add the necessary codes and stamp, copy it, and give you back the original. You will get back the completed application and a transaction recipt. Now what i also do, is Photocopy the 2 originals on to one page double sided and keep that with me. I put the originals in my filing cabinet. Since Massachusetts does not title mopeds its a good way to prove your ownership, and ownership history.
