Used motorcycles in Thailand: paperwork, transfer and inspection
Used motorcycles trade easily, but almost every problem comes from the paperwork, not the engine. Finish the document checks before paying, then inspect the bike. That order matters more than people expect.

Documents to complete before paying
- The original registration book, with the holder's name matching the seller's ID card.
- If finance is outstanding, it must be cleared first, or the contract must state who pays the remainder and when the book is handed over.
- Annual tax and compulsory insurance (Por Ror Bor) must be current. If lapsed, establish the back-penalty amount and who pays it.
- The frame and engine numbers on the bike must match the book digit for digit. Any mismatch or scratched number means walk away immediately.
- A power of attorney and a copy of the seller's ID if you are not going to the transport office together.
Transferring ownership
Transfer happens at the Land Transport Office of the province where the bike is registered. Different province means filing a relocation first. The safest route is for both parties to attend together on the day of payment.
If you go separately, you need a sale contract, a signed and certified copy of the seller's ID, and a power of attorney. Keep copies of everything yourself.
Never buy a bike the seller describes as "no book, but it runs fine". It cannot be transferred or taxed, and may carry legal problems.
Inspecting the bike
- Start it from cold and listen to the first seconds. Knocking or heavy white smoke means internal engine trouble.
- Check the chain, sprockets, brake pads, tyres and both suspension ends for oil seepage.
- Push down on the bars and take a short test ride: look for pulling to one side, brake judder or difficult gear changes.
- Inspect the frame under the plastics. Fresh welds or unusually thick overspray suggest a serious crash.
- Treat the odometer as one data point only; compare it with real wear on the footpegs, bars, seat and switches.
Pricing and selling well
Prices in Thailand depend more on which models are popular locally than on the production year. Bikes with easy parts availability and many service shops fetch visibly better prices.
Sellers should attach a photo of the registration book (personal details covered), the odometer, both sides of the engine, and recent service history. Listings like that get higher prices and more enquiries.
If tyres, chain, sprockets or battery were recently replaced, give the dates. Buyers pay extra for items they will not have to redo immediately.
