The more people I ask, the more contradictory information I receive. Many people say that when buying a motorcycle in Thailand, you do not need to register it. In my country I didn't register my cars either, even though it was theoretically necessary and the police never caused a problem. How is it here? One guy has a nice motorcycle at a good price but only has a copy of the green book. He says that all I need to bring is the purchase contract, bill, driving license and tax. Is it true?
