According to the letter of the law in Ohio, legally you must transfer the title of the vehicle into your name before selling it to another party.
The basic rule in Ohio is that you are not allowed to sell any type of motorcycle without a title.
--If after 1999 and vehicle is from Ohio, you are required to transfer title into your name before selling to another party
--If prior to 1999, you are required to get a title made before selling in Ohio.
--If from out of state, you are required to change into Ohio title before selling.

Again, all that is how the laws are written for what you are supposed to do. Do people follow all of that? You tell me.
