Buying a pre-owned motorcycle in Singapore can feel like navigating a complex financial maze. With Certificate of Entitlement (COE) premiums fluctuating and shop loan interest rates eating into monthly budgets, riders frequently seek alternative ways to get on two wheels without breaking the bank.
If you have spent any time browsing classifieds on Carousell, Facebook Marketplace, or local motorcycle forums, you have likely come across the term COI—short for Carry On Installment.
While COI deal arrangements offer a fast path to owning a bike with minimal upfront cash, they also carry distinct legal and financial risks for both buyers and sellers. This guide breaks down what COI actually means, how the process works step-by-step, its pros and cons, and the essential safety steps you must take before signing any agreement.

What is COI (Carry On Installment)?
In Singapore’s motorcycle community, COI (Carry On Installment) refers to a subletting or loan-takeover arrangement between a seller and a buyer.
When a rider purchases a motorcycle through a dealership hire-purchase loan, the bike remains under an active financial lien. If the seller decides to sell the motorcycle before clearing their remaining loan, they face two options:
- Pay off the outstanding loan in full (which often incurs heavy early settlement penalties).
- Find a buyer willing to carry on the remaining monthly installments directly.
Under a standard COI deal:
- The buyer pays the seller an agreed upfront cash amount (representing the seller’s equity or negotiated takeover fee).
- The buyer takes physical possession of the motorcycle and agrees to pay the existing monthly loan installments.
- The legal ownership registered with the Land Transport Authority (LTA) remains in the seller’s name until the final loan payment is cleared.
Crucial Distinction: COI is an informal private agreement between individuals. Under official LTA Vehicle Transfer Guidelines, a vehicle with an active financing lien cannot be officially transferred to a new owner until the underlying hire-purchase loan is settled in full.
How COI Works in Practice: Step-by-Step
Understanding the exact sequence of a COI transaction helps prevent misunderstandings down the road.
[Seller has active shop loan] ➔ [Buyer pays Upfront Cash] ➔ [Sign Subletting Agreement] ➔ [Buyer added as 2nd Rider] ➔ [Buyer pays Monthly Installments] ➔ [Loan Cleared] ➔ [Official LTA Transfer]
Step 1: Negotiating Upfront Cash & Monthly Terms
The seller advertises the bike with two figures: the Upfront Cash (e.g., $2,500) and the Remaining COI (e.g., $280/month for 18 months). The buyer pays the upfront cash directly to the seller.
Step 2: Drafting a COI / Subletting Agreement
Because LTA will not recognize the buyer as the legal owner yet, both parties sign a private contract—often called a Letter of Subletting or COI Agreement. This document outlines the payment schedule, responsibilities for traffic fines, maintenance obligations, and the commitment to transfer ownership upon final payment. Standard templates are available online via platforms like Motorist Singapore.
Step 3: Updating Insurance & Sub-Rider Details
The buyer must be legally covered to ride the machine. The primary insurance policy usually stays in the seller’s name, but the buyer is officially added as an Authorized Sub-Rider / Second Rider. Alternatively, a fresh insurance policy naming the buyer as the primary rider is tied to the vehicle’s registration number.
Step 4: Servicing the Monthly Installments
Every month, the buyer pays the installment. Depending on the arrangement made with the motorcycle shop, the buyer either pays the shop directly or transfers the money to the seller to pass along to the lender.
Step 5: Final Loan Settlement & Official LTA Transfer
Once the last monthly payment is made, the motorcycle dealership clears the financial lien in the LTA system. The seller then logs into LTA’s OneMotoring portal to initiate the official ownership transfer to the buyer for a standard S$25 administrative fee.

Pros and Cons of COI
Before entering into a COI agreement, evaluate the benefits against the potential liabilities.
| Feature / Aspect | Pros | Cons |
| For Buyers | • Low Capital Barrier: Requires significantly less upfront cash than buying outright. • No Credit Checks: Avoids strict bank/shop loan approvals or needing a guarantor. • Fast Handover: Get riding immediately without waiting for formal loan underwriting. | • No Legal Title: You do not legally own the bike until the final dollar is paid. • Repossession Risk: If the seller defaults on other debts, the bike could be repossessed. • Seller Trust Dependency: You rely on the seller to actually pay the shop and complete the eventual LTA transfer. |
| For Sellers | • Avoid Settlement Penalties: Bypasses heavy early loan termination fees. • Quick Exit: Pass monthly loan obligations to another rider if you can no longer afford them. • Recover Equity: Recoup a portion of the downpayment made previously. | • Fine & Legal Liability: Traffic fines, summon letters, and ERP violations initially come under your name. • Default Exposure: If the buyer stops paying or disappears, the lender will legally pursue you for the debt. |
Critical Risks & What to Watch Out For
While COI transactions are common, they operate in a legal gray area. Here are the most critical pitfalls riders face and how to safeguard against them.
1. The Legal Title & Repossession Trap (Buyer Risk)
Because the motorcycle remains registered under the seller’s NRIC with LTA, you do not own the bike during the COI period.
- If the seller files for personal bankruptcy, gets involved in legal disputes, or passes away, creditors may seize the motorcycle as part of the seller’s assets—even if you have been paying every monthly installment on time.
- If the seller takes your monthly payments but fails to forward them to the motorcycle dealership, the shop has the legal right to repossess the bike from your carpark.
2. Traffic Offenses & Summons (Seller Risk)
Speeding camera flashes, red-light cameras, and parking summonses are automatically issued to the registered owner. As the seller, if your COI buyer incurs heavy fines and refuses to pay, LTA and the Traffic Police will hold you legally responsible until you submit an official driver declaration proving you were not operating the vehicle.
3. Breach of Hire-Purchase Agreement
Most motorcycle dealership hire-purchase contracts explicitly prohibit sub-leasing or transferring possession of the vehicle to a third party without prior written consent from the finance company. If the shop discovers the bike is being ridden under an unauthorized COI, they may demand immediate full settlement of the remaining balance.
Best Practices: How to Protect Yourself in a COI Deal
If you decide to proceed with a COI deal, follow these strict precautions to minimize risk:
- Pay the Shop Directly: Avoid transferring monthly installments to the seller’s personal bank account. Request to pay the motorcycle shop or finance company directly under the agreement account number, and keep every digital receipt.
- Execute a Legal Subletting Contract: Draft a clear written agreement detailing both parties’ NRICs, engine/chassis numbers, payment schedules, and explicit clauses stating that all traffic offenses incurred after the handover date belong to the buyer.
- Verify Insurance Coverage: Ensure the buyer is formally listed as a named rider on the insurance policy so that claims are honored in the event of an accident.
- Inspect the Bike at an Independent Workshop: Perform a full mechanical check before paying any upfront cash. Resolving pre-existing mechanical issues after taking over a COI can cause disputes over who should pay for repairs.
- Consider Shop Refinancing Instead: Whenever possible, approach the motorcycle shop to officially transfer or refinance the loan into the buyer’s name. While this may incur administrative fees, it eliminates ownership risk by establishing official LTA title transfer right away.
