What this document is
Across Southeast Asia, the motorbike is the family vehicle, and second-hand bikes change hands between individuals every day — a used Honda Click might sell for THB 28,000 in Thailand, a Vario for IDR 14,000,000 in Indonesia, or a scooter for PHP 45,000 in the Philippines. A motorcycle sale agreement records the essentials of that deal: the bike's identity, its registration book, the price, and how ownership actually transfers.
Motorbikes carry two risks that make paperwork especially important. First, many are bought on installment plans, and the finance company keeps the registration book until the last payment — a bike sold before payoff cannot be transferred to the buyer's name. Second, plates and papers are easier to mismatch or fake than with cars, so the agreement should copy the engine and frame numbers directly from the bike and the book, not from the listing.
When to use it
- Selling your motorbike to another rider through a marketplace app, a repair shop noticeboard, or word of mouth.
- Buying a second-hand bike from a private seller and wanting proof of the price, the mileage, and the promise to transfer the book.
- Selling a bike that still has installments owing, where the payoff to the finance company is part of the deal.
- Taking a deposit to hold the bike while the buyer gathers the rest of the money.
- Selling a bike together with helmets, a top box, or riding gear that should be listed so nothing is disputed at handover.
- Selling a family member's bike on their behalf with their written authorization.
When not to use it
- The seller cannot show the registration book or an explanation of where it is — a missing book is a serious red flag, not a paperwork detail.
- The engine or frame number does not match the book. Stop the deal and check with the transport office before any money moves.
- The bike is part of an inheritance or divorce that has not been settled — ownership needs resolving first.
- You are a dealer selling bikes as a business, where different tax and consumer rules apply.

Motorcycle identification
Records plate, engine, and frame numbers exactly as verified on the bike and in the registration book.

Price and payment
Sets the total price, deposit, and balance, with each payment confirmed by receipt or transfer slip.

How to sign it
Sign two copies at the point of sale, one for each side. If a deposit is paid first, sign the agreement then, and add a signed receipt each time money changes hands — many bike sales are cash sales, and without receipts the seller can later deny receiving the full amount, or the buyer can claim to have paid more.
At handover, photograph the bike, the odometer, the engine and frame numbers, and the registration book alongside the signed agreement. If the book is with a finance company, do not complete the purchase until you have written confirmation of the payoff amount and how the book will be released.
Do the name transfer promptly — in most countries either both parties attend the transport office, or the seller hands over signed transfer forms and copies of their ID. Until the bike leaves the seller's name, fines and accident liability can still reach them, so a firm transfer deadline protects the seller as much as the buyer.
Common mistakes
- Buying a bike whose book is 'with the finance company' without confirming the payoff amount directly with that company.
- Paying the full price in cash with no signed receipt, leaving no proof the money was ever handed over.
- Trusting the plate number instead of checking the engine and frame numbers against the book.
- Forgetting to list the helmet, top box, and spare key, then arguing about them at handover.
- Skipping the name transfer to save the fee, leaving the seller exposed to the buyer's fines and accidents.
Frequently asked questions
Do I need a contract to sell my motorbike privately?
In most countries a private bike sale can legally happen with just the transfer paperwork, but a signed sale agreement is what protects you when something goes wrong — a disputed price, an undisclosed installment balance, or a buyer who never transfers the name. For a deal worth tens of thousands of baht or millions of rupiah, ten minutes of writing is cheap.
Can I sell a motorbike that I am still paying installments on?
Only by dealing with the finance company, because it holds the registration book until the loan is cleared. The usual route is that the buyer's payment settles the remaining balance first, the book is released, and the transfer follows. Never sell 'off the books' by just handing over the bike — the buyer can never register it, and you remain liable for it.
How do I check the bike is not stolen before buying?
Match the engine and frame numbers on the bike against the registration book, check the seller's ID against the name in the book, and be suspicious of prices far below market or a missing book. In many countries the transport office can confirm the registration record — doing the name transfer together at the office is itself a strong check.
The buyer wants to pay half now and half next month. How do I stay safe?
Keep the bike and the registration book until the final payment, and write the schedule into the agreement with a signed receipt for each installment. If the buyer insists on taking the bike early, at minimum keep the book and state in writing that ownership transfers only on full payment. For longer plans, use an installment payment agreement.
Who pays the transfer fee at the transport office?
There is no fixed rule — it is whatever the parties agree, and the agreement should say so explicitly. A common practice is that the buyer pays the transfer fee while the seller provides all documents and signatures. What matters most is agreeing it before money moves, not after.
What should the buyer receive at handover?
The bike and all keys, the registration book or the agreed proof it is being released, signed transfer documents and ID copies as required locally, and any included gear. The buyer should also leave with a signed receipt for every payment made — that pile of paper is what turns a stranger-to-stranger deal into a safe one.
