Motorcycle Bill of Sale: What It Is, What It Should Include, and Why It Matters

When you buy or sell a motorcycle, a bill of sale is one of the most important documents in the transaction. It's a written record that a sale happened — capturing who sold what, to whom, for how much, and when. Depending on your state, it may be required to transfer the title, register the bike, or simply protect both parties if a dispute comes up later.

What a Motorcycle Bill of Sale Actually Does

A bill of sale is not a title. It doesn't transfer legal ownership on its own. What it does is document the terms of the transaction — and that documentation matters for several reasons:

• It gives the buyer proof of purchase while the title transfer is being processed
• It protects the seller from liability if the buyer doesn't register the bike and later gets a ticket or causes an accident
• It establishes the purchase price, which some states use to calculate sales tax or use tax owed at registration
• It can help resolve disputes about what was agreed to

Some states require a bill of sale as part of the title transfer process. Others treat it as optional but strongly recommended. Either way, skipping it creates unnecessary risk for both sides.

What a Motorcycle Bill of Sale Should Include

There's no single universal format, but most states and most private-sale situations call for the same core information:

The VIN is especially important. It ties the bill of sale to a specific motorcycle — not just a model, but the exact bike. Always verify the VIN on the frame matches what's on the title before signing anything.

When the Sale Price Says "$1" 🏍️

Private sellers sometimes list a low or symbolic price on a bill of sale — especially in family transfers — to reduce the buyer's tax burden. Many states have caught on to this. Some now require the fair market value to be used for tax purposes regardless of what the bill of sale says, and others cross-reference prices against valuation guides. Understating a sale price on official documents can create legal problems, so it's worth knowing your state's rules before trying this.

Gifted Motorcycles and No-Sale Transfers

If a motorcycle is being gifted rather than sold, the bill of sale still serves a purpose. It documents that no money changed hands — which can matter for tax exemptions — and it still records who transferred the bike and who received it. Some states have a specific gift affidavit or form for this situation instead of a standard bill of sale.

Notarization: Required or Optional?

Whether a motorcycle bill of sale needs to be notarized depends on the state. Some states require notarization for title transfers on motor vehicles, including motorcycles. Others don't require it at all. A few states have separate notarization requirements based on the vehicle's value or the buyer's state of residence.

Even where it's not legally required, notarization adds a layer of authenticity — it confirms that the signatures are real and the parties were who they said they were. This matters most in situations where someone might later dispute whether a sale happened.

What Happens When There's No Title

Buying a motorcycle without a title is a genuine complication. A bill of sale alone doesn't replace a title — it can't be used to register the bike in most states. Some states have a process to obtain a bonded title or replacement title using a bill of sale as supporting documentation, but that process varies considerably. In some states it's a workable path; in others it's a long road involving surety bonds, waiting periods, and DMV hearings.

If a seller can't produce a title, the bill of sale at minimum helps establish a paper trail — but it doesn't resolve the underlying ownership question.

State-by-State Variation Is Significant

Some states provide an official bill of sale form for motorcycle transactions. Others let you use any written document as long as it contains the required information. A handful of states fold bill-of-sale information into the title transfer paperwork itself.

The differences don't stop at format:

• Notarization requirements vary
• Which fields are mandatory varies
• Whether the bill of sale triggers sales tax varies
• Whether it's required to register varies

Your state's DMV or motor vehicle agency is the authoritative source on what's required in your jurisdiction. Some states publish sample forms online — searching your state's DMV website for "motorcycle bill of sale" is usually the fastest way to find them.

Keeping Copies

Both parties should retain a copy of the signed bill of sale. For the seller, it's the record that you transferred the vehicle and what terms were agreed to. For the buyer, it's the bridge document while the title is being transferred and the registration is being processed.

How long you keep it is a judgment call — but holding onto it for at least as long as any title dispute could reasonably arise is a reasonable approach.

The specifics of what your state requires, whether your transaction calls for notarization, and what tax implications apply all come down to where you are and the details of the sale itself.
