Buy and sell in the U.S.

[Nachodaddy]

You are correct to think that each state in the US has very different procedures and requirements. I am in Arizona and only recently Arizona Department of Transportation (ADOT) has stopped issuing a paper title when you purchase a vehicle. An electronic record is kept and you can get a paper title if you request it, but you receive no paper title when you buy a vehicle. When you sell that vehicle, you and the buyer go to the ADOT office (or other authorized contractor) and they will look up the title and electronically issue the title to the new owner, but he/she will also not get a paper title unless specifically requested. No longer can you simply sign and notarize your title and hand it to the buyer unless you order a paper title in advance and have it ready when you make the sale. Each state has different ways of doing things. One thing that may help you is to go on-line and see what the requirements are for the state you plan to buy the bike and re-sell it and see what the requirements are for that state. Good luck and happy traveling.
When I lived in Las Vegas I know you could rent a motorcycle (or an exotic car, like a Ferrari or Lamborghini) if you were from out of the country, but I do not know any of the details.
