What documents are required to register a motorbike in Thailand?

To register a motorbike in Thailand, you will need to present a variety of documents at the Land Transport Office. These include: 1. The motorbike itself. 2. The vehicle ownership booklet (green book). 3. Your passport, along with signed copies of the passport info and visa pages. 4. A residence certificate from Immigration or your embassy, or alternatively, a work permit. 5. An application form signed by the seller. 6. If the seller is Thai, you'll need a signed copy of their national ID, or if they are foreign, a signed copy of their passport info and visa pages. Additionally, having the current owner present can simplify the transfer process.
