Used motorbike checklist Thailand: papers, engine number, tax, insurance
Used motorbikes are one of the most traded items on Near Dee. Most problems come not from the engine but from paperwork that does not match, or a bike still tied to a finance company. This guide orders what to check before you agree on a price.

1. The registration book must match the bike and the seller
Always ask for the original registration book (blue book), never buy from a photo alone. Compare the registered owner's name to the ID card of the person selling. If they do not match, ask whether this is a resale from the original owner and make sure a power of attorney or a chain of sale documents exists, otherwise the DLT will refuse to process the transfer.
Check the book is not a reissued or reported-lost copy by looking at the DLT stamp and officer's signature on the most recent transfer page. If the bike was transferred very recently, ask why directly.
2. Match the chassis and engine numbers to the book
The chassis number is usually stamped under the seat or near the steering neck; the engine number is on the engine block. Every digit must match the registration book exactly. If a number looks scraped, re-stamped, or welded over, walk away — this often signals a bike with a disputed origin, and the DLT will reject the transfer.
3. Check finance status and any legal claims
A bike still under an instalment plan lists the finance company as the legal owner in the book. If the seller claims it is paid off, ask for the finance company's clearance letter or final settlement receipt and check it against the book before paying in full. If the loan is not actually closed, the finance company can repossess the bike even after you have paid the seller.
4. Test ride and inspect properly
- Start the engine cold, not after the seller has already warmed it up, and listen to the cold start.
- Compare the odometer reading against tyre and brake wear — unusually low mileage with heavily worn tyres is a red flag.
- Look for crash damage or welding on the frame, and check the handlebars and forks are straight.
- Ride it on the road: test front and rear brakes, clutch, and every gear.
5. Annual tax and compulsory (Por Ror Bor) insurance
Check the tax disc on the front is not expired, and ask for the latest compulsory insurance receipt. If tax lapses for more than 3 years, the registration is suspended and re-registering is far more troublesome. Negotiate the price down if tax is about to expire, since you will need to renew it immediately after transfer.
6. The transfer process at the DLT office
Both buyer and seller need to visit the Department of Land Transport office with original ID cards, the registration book, and the actual bike so an officer can verify the chassis and engine numbers. Transfer fees run roughly ฿100-300 depending on vehicle type and province. If the seller cannot attend, a notarised power of attorney with a signed ID copy is required.
7. Realistic price ranges
Prices vary heavily by model, year, and mileage, but as a guide: 110-125cc commuter bikes 3-5 years old run roughly ฿18,000-35,000, big-scooters around 150-160cc of similar age run roughly ฿45,000-90,000, and used big bikes vary enormously by brand, starting from around ฿120,000. Compare several listings before deciding.
