Selling a vehicle without a notary?

Hi, I sold my motorcycle to someone recently and I have a question. Myself and the buyer signed the title and signed an agreement stating that I willingly relinquished the vehicle to the buyer and that the buyer has 30 days to transfer the title into their name. I did not have the title or agreement notarized. I am from Oklahoma and have never had to notarize a title, you just signed it and that was it, But here (ohio) I have heard that you need it notarized to transfer a title. Will this cause problems for me even though I willingly signed over the bike?
