Motorcycle sales to Hungary

Hello, here’s the matter. I’m currently selling my motorcycle. Now someone from Hungary has called me. I’ve been on the phone with him for a long time and actually everything is unsuspicious. I’m also rather careful but also not panicky. I definitely don’t have the feeling that I’m supposed to be wrong here. So nothing with pre-transfer via Western Union, pick-up by an acquaintance or by forwarding, etc. He wants tomorrow with a Ford Tra nsit come and if everything is ok that motorcycle take with you. My question is rather about how this is handled with license plates, registration, license letter and bill? I would hate to log off the motorcycle today, because I can’t be sure that he actually buys it. If not, then I have a registered motorcycle in the garage. Ok, if he buys it, I will of course remove the license plate. But what about the papers? If I have the moped, let’s say, then at the F What do I need for this? I don’t have a letter. How would you handle it the most ideal way? Mfg
