Motorcycle Bill of Sale: What It Is, What It Should Include, and How It Works
A motorcycle bill of sale is a written record of a private transaction between a seller and a buyer. It documents that ownership of a motorcycle changed hands, for what price, and under what conditions. Most states require some version of this document when registering a used motorcycle — and even when they don't require it, having one protects both parties if a dispute arises later.
What a Motorcycle Bill of Sale Actually Does
The bill of sale serves two main functions. First, it gives the buyer proof they legally acquired the motorcycle. Second, it gives the seller documentation that they transferred ownership — which matters if the bike is later involved in an accident, unpaid tolls, or crimes after the sale.
It's not the same as a title. The title is the legal ownership document issued by the state. The bill of sale is the transaction record. In most cases, you need both to complete a proper transfer — the title signed over to the buyer, and the bill of sale as supporting evidence of the deal.
What a Motorcycle Bill of Sale Should Include
Requirements vary by state, but a complete bill of sale typically covers:
| Field | Why It Matters |
|---|---|
| Seller's full name and address | Establishes who transferred ownership |
| Buyer's full name and address | Establishes who received it |
| Sale date | Starts the clock on registration deadlines |
| Sale price | Used by some states to calculate sales tax |
| Motorcycle year, make, and model | Identifies the specific bike |
| VIN (Vehicle Identification Number) | The definitive identifier — critical |
| Odometer reading | Required in many states; documents mileage at time of sale |
| Condition notes or "as-is" language | Protects seller if buyer discovers problems later |
| Seller's signature | Makes the document valid |
| Buyer's signature | Acknowledges terms of the sale |
Some states also require the document to be notarized — meaning both parties sign in front of a licensed notary who verifies identities. Others accept a simple signed document. A few states have official bill of sale forms available through the DMV; some accept any written document that includes the required fields.
When You Need One 📋
The most common situations where a motorcycle bill of sale comes up:
- Buying or selling a used motorcycle privately — dealer transactions typically generate their own paperwork, but private sales rely on a bill of sale
- Registering a recently purchased motorcycle — the DMV may ask for it alongside the signed title
- Transferring a motorcycle received as a gift — the sale price would be listed as $0 or the fair market value depending on state rules
- Registering a motorcycle with a lien release — if a previous owner financed the bike, the bill of sale helps establish when that relationship ended
- Replacing a lost title — a bill of sale alone usually can't substitute for a title, but it can support a bonded title application in some states
How Sale Price Affects Taxes
Many states charge use tax or sales tax on private vehicle sales, calculated from the sale price listed on the bill of sale. This is one reason the document matters to the DMV — it's not just about proving the transfer happened, but about establishing the taxable amount.
Some states will apply their own minimum valuation (often based on the vehicle's book value) if the declared sale price seems unusually low. Listing an artificially low price to reduce taxes can create problems during registration and may constitute fraud.
"As-Is" Sales and Seller Protections
Most private motorcycle sales are sold as-is, meaning the seller makes no warranty about the condition of the bike. Including clear as-is language in the bill of sale helps establish that the buyer accepted the motorcycle in its current state, with no obligation from the seller to cover future repairs or defects.
This doesn't give sellers license to conceal known defects — many states have laws against misrepresentation in vehicle sales — but it does document that the buyer wasn't promised a perfect machine.
Variables That Change What You Need 🔍
There's no single universal bill of sale form that works in every state. What you need depends on:
- Your state's specific DMV requirements — some have mandatory forms, others don't
- Whether the motorcycle is titled or untitled — older bikes, especially those built before a certain year, may not have had titles issued in some states
- Whether there's an active lien on the bike — a loan that hasn't been paid off complicates the transfer
- Whether the sale is a gift, trade, or cash transaction — each may be handled differently for tax purposes
- The motorcycle's age — federal odometer disclosure requirements only apply to vehicles under a certain age, though states may have their own rules
Notarization requirements, accepted form formats, and what the DMV will ask for at the window all depend on where you live and where the bike was previously registered.
What Happens After the Sale
Once the bill of sale is signed, the buyer typically has a limited window — often 10 to 30 days depending on the state — to register the motorcycle and pay any applicable taxes or fees. Missing that window can result in late fees. The seller should notify their state DMV that the vehicle was sold, which in many states protects them from liability for anything that happens after the transfer date.
The bill of sale doesn't replace the title, doesn't automatically transfer registration, and doesn't cancel the seller's existing insurance — those are separate steps that each party handles independently.
What the document is, how much detail it needs, and how your DMV will use it when you walk in — that depends on your state, the motorcycle's history, and the specifics of your transaction.
