Buying a Used Motorbike in Thailand

Buying a used motorbike in Thailand is quick, cheap and mostly informal — and the informality is the whole risk. The machine itself is rarely the problem: Thailand is full of well-maintained small automatics with parts available in every town. What goes wrong is the paperwork. The single question that decides whether a purchase is sound is whether the seller can hand you the green registration book with their own name in it and sign a transfer at the land transport office alongside you.

Everything else — mileage, tyres, a rattling exhaust — is negotiable or fixable. A bike sold without its book, or with someone else's name in it, is not a bargain with a snag; it is a bike you may never be able to register, tax, insure or legally sell.

What you are actually buying

Two things: a machine, and a place in a register. The machine you can assess yourself, and our used motorbike checklist is written to be used standing next to the bike. The register entry you assess by reading the green book, and that is the part most foreign buyers skip.

The green book records the plate number and the province that issued it, the frame and engine numbers, the make, model, colour and engine size, the date of first registration, the annual tax payment history, and every ownership transfer since the bike was new. It also distinguishes two roles that English does not: the title holder, who owns the machine, and the possessor, who keeps and uses it. If the bike was bought on finance and the loan is not settled, the finance company is the title holder and the seller cannot transfer anything. The Thai logbook, page by page explains what each entry means.

Which bikes to look at

The Thai used market is dominated by a small number of models, which is good news: parts, mechanics and a resale market all exist for them. The 110–125cc step-throughs and small automatics — the Wave, the Click, the Scoopy, the Fino, the Mio — are the everyday machines, cheap to run and cheap to fix. The 150cc automatics such as the PCX, the ADV, the Aerox and the NMAX are heavier, faster, more comfortable two-up and noticeably better on hills, and cost proportionately more.

If you are riding in Chiang Mai, on Koh Phangan, on Koh Chang or anywhere with real gradients, the extra capacity is not a luxury; a fully loaded 110 struggles on the steeper climbs and its brakes are working harder on the way back down. Our comparison of 110cc against 150cc was written for renters but the reasoning is identical for a buyer. Anything over 400cc puts you in "big bike" territory, where price, insurance and the licence question all change — check the Thai motorbike licence and engine sizes.

Where to look

Dealer forecourts, second-hand markets, expat Facebook groups, Thai classified apps and hostel notice boards all sell bikes, on a clean spectrum from expensive-and-safe to cheap-and-risky. Where to buy a used car or bike compares them properly. For a first-time buyer: a shop that sells bikes as its actual business has a reputation in the town and will usually do the transfer for you, which is worth a premium. The riskiest purchases carry the most urgency — a traveller selling on Friday for a Sunday flight has every incentive to gloss over the book, and no address you can return to.

What a fair price looks like

Prices vary by model, condition, year, province and how badly the seller wants out. Advertised prices on the Thai classified sites are the best guide and are easy to check on a phone while you stand there. As a shape rather than a promise: tidy older 110cc step-throughs occupy the bottom of the market, recent 125cc automatics sit noticeably higher, and 150cc machines higher again. What a used car or motorbike really costs goes into the ranges.

Two things move the price legitimately. A bike with a clean book, current tax and current compulsory insurance beats the same bike with three years of unpaid tax, because you will be paying that off. And a bike registered where you live is worth more to you than one on plates from the other end of the country — see buying a vehicle registered in another province.

The checks that matter before money changes hands

• Frame number on the bike matches the frame number in the green book, digit for digit
• Engine number on the bike matches the green book
• The name in the book is the person standing in front of you, and their ID confirms it
• No finance company recorded as title holder
• The tax history in the book runs up to date, or you know exactly how far behind it is
• Compulsory insurance (Por Ror Bor) certificate is present and in date
• The tax sticker date matches what the book says
• Plate on the bike matches the plate number in the book
• No sign the numbers have been ground, restamped or plated over
• The seller agrees, in advance, to attend the land transport office with you

If any number does not match, stop. Mismatched or tampered numbers are the signature of a stolen or cloned machine, and how to avoid buying a stolen or cloned vehicle explains what the tampering looks like and why the loss falls on you rather than the seller.

Doing the transfer

The transfer happens at a Department of Land Transport office, with the bike physically present for a short inspection of its numbers. Both parties sign; in practice a signed power of attorney is often used so that only one person has to attend, but a private buyer should be wary of anything that means the seller never appears at all.

The costs are small: an application fee of about ฿5, a transfer fee of around ฿100, a motorcycle inspection fee of about ฿10, and stamp duty at roughly 0.5% of the value the DLT puts on the bike. New plates, if you are also moving the registration to another province, add about ฿200. Those fee figures come from consistent Thai commercial sources rather than a ministerial schedule we could read, so treat them as approximate. Transferring vehicle ownership at the DLT walks through the visit.

After you own it

Three obligations follow the bike, in order. Compulsory third-party insurance must be in force before the annual road tax can be paid — Por Ror Bor explains what it covers, which is people and not property. Once the bike is more than five years old, it needs an annual roadworthiness test before the tax can be renewed; the fee is ฿60. The tax itself is paid a year in advance, with a surcharge of 1% per month if you are late.

Voluntary insurance is separate. On a cheap bike, comprehensive cover rarely pays for itself, but third-party liability almost always does — which insurance class to buy for a used motorbike.
