About the Dirt Bike Bill of Sale

A dirt bike bill of sale records the private sale of an off-road motorcycle: a motocross bike, an enduro, a trail bike or a pit bike. Dirt bikes sit between cars and toys in state law. Some states title them, some only register them for off-road riding, and some do neither. In those last states the bill of sale may be the only ownership paper the buyer gets, so it needs the VIN or frame number, the engine number, and both signatures.

When to Use This Form

Use this form for any off-road motorcycle sold between private parties. If the bike is titled, also sign the title over; the bill of sale adds the price, the date and the as-is terms. For a street-legal dual-sport bike that is registered for the road, the car-style rules apply, so use the motorcycle bill of sale instead.

Legal Tip

Copy the VIN or frame number from the bike itself and check it against the title or registration before you pay. Also write down the engine number. California asks for both numbers on motorcycle registration papers, and Oregon accepts an engine serial number when a bike has no VIN.

How states handle dirt bikes (examples we checked)

  • California: the DMV issues a title plus an off-highway ID (a green or red sticker) instead of a plate. The buyer pays the transfer fee within 30 days, use tax applies, and no smog certificate is needed. Bikes from 2003 on with a "3" or "C" in the 8th VIN position are red-sticker bikes (tan for 2022 and newer). They have limited riding seasons and can never be registered for the street.
  • Washington: off-road bikes are titled, and the buyer has 15 days to apply for the title before penalties. Off-road registration lasts one year, and the decals must be on the bike.
  • Oregon: a dirt bike ridden off-road is a Class III ATV. A title is optional, and the $10 riding permit, good for two years, needs only the VIN.
  • Arizona: state law names dirt bikes as off-highway vehicles. Riding one needs an off-highway decal from ADOT, valid for one year.
  • Minnesota: off-highway motorcycles must be registered before they are ridden. Registration is $45 for three years, and a transfer is $4 plus a filing fee.

Making a dirt bike street legal

This is where many buyers get caught out. In California, an off-highway-only motorcycle cannot be converted to road use unless it was built as a dual-purpose bike. Oregon says a dual-sport kit alone is not enough; you need the maker's papers showing federal emissions compliance.

Washington and Arizona offer a route. In Washington the bike gets the required equipment, passes a licensed-shop inspection (up to $100), and its title is marked "modified for on-road use." In Arizona, an owner with the off-highway decal can sign an affidavit that the bike meets the road equipment rules. Minnesota allows dual registration for a properly equipped bike. If the seller says a bike is street legal, ask to see the title or registration that proves it.

What to write on a dirt bike bill of sale

  6. Price, how it was paid, and whether the bike is sold as-is.
  7. Both signatures.

Frequently Asked Questions

Do I need a bill of sale to sell a dirt bike?
In some states the law requires one, and everywhere it is wise. Minnesota requires an off-highway motorcycle to be transferred with a bill of sale that lists the serial number, signed by the seller and buyer, within 15 days. In states that do not title dirt bikes, such as Oregon, where titling is optional, the bill of sale is often the only proof of ownership.
How do I make a bill of sale for a dirt bike?
List the seller and buyer names and addresses, the date and price, and the year, make and model. Add the VIN or frame number and the engine number, plus any off-road sticker or permit number, and have both people sign. You can type it with the form on this page or write it by hand.
Can I get a title with a bill of sale on a dirt bike?
Sometimes. Where dirt bikes are titled, the buyer normally needs the seller's signed title; California asks for the certificate of title, or a duplicate-title application if it was lost. For an off-road bike that was never registered, California accepts bills of sale that show the chain of ownership. Ask your state before you buy a bike that has no paperwork.
Does a dirt bike sale need an odometer disclosure?
Not under federal law if the bike is off-road only. The federal odometer law covers vehicles made mainly for public roads, and an off-road dirt bike is not one of them. California also says a bike built without an odometer needs no odometer disclosure, even when it is converted for road use. Write down the hours or miles anyway if the bike has a meter.
Can you handwrite a bill of sale for a motorcycle?
Yes, in the states we checked. Virginia's DMV says a bill of sale can be a handwritten statement signed by the seller and buyer, and California accepts any bill of sale that identifies the vehicle, with no notary or witness. Write clearly and include the VIN or frame number and the engine number.
