Your Montana motorcycle post-sale checklist
- 1
Keep your signed Montana bill of sale
This is your proof that you sold the motorcycle on the sale date. If the buyer gets a ticket, is in an accident, or fails to transfer the title within 40 days from the sale date, the Montana bill of sale shields you from liability. Keep both your copy and a scan for at least 5 years.
- 2
File a release of liability with Montana DMV
Most Montana sellers file this online through Montana DMV within 5 days of the sale. Filing removes you from records as the registered owner so any post-sale tickets, tolls, or accidents become the buyer's responsibility, not yours. Montana requires the buyer to title the motorcycle within 40 days — your release filing protects you if the buyer misses that deadline.
- 3
Cancel or transfer your motorcycle insurance
Contact your insurer the same day you hand over the keys. Montana does not require you to maintain insurance on a vehicle you no longer own, but you must not cancel before the sale is complete. If you are replacing the motorcycle with another, transfer the policy instead — many insurers offer a short grace period to bind coverage on the new vehicle.
- 4
Remove your license plate
In Montana, plates go with the seller — not with the motorcycle. Remove the plate(s) before the buyer drives or rides away. You can return them to Montana DMV or transfer them to your next vehicle.
- 5
Verify the 40-day title transfer window
Montana requires the buyer to retitle the motorcycle at Montana DMV within 40 days of the sale date. If you have not received confirmation that the title has been transferred by day 45, contact Montana DMV with your bill of sale and release-of-liability filing number to confirm the change of ownership.
- 6
Confirm your Montana tax obligations (seller's side)
Montana does not impose state sales tax on private-party motorcycle sales (Montana has no state sales tax on any purchases). The buyer typically pays a flat title fee (~$12) at Montana DMV. If you sold the motorcycle for more than your original purchase price, you may owe federal capital gains — most private motorcycle sales are at a loss and not taxable.
- 7
Watch for liens or loan payoff confirmation
If you had a loan on the motorcycle, confirm the lender received the buyer's payoff and has released the lien on the Montana title before you deliver the title. Montana uses MV21 (Title Lien Notation Release) as the lien release form — your lender will file this with Montana DMV to clear the title record.
Motorcycle-specific note
Motorcycles use a 17-character VIN stamped on the frame near the steering head — confirm it matches the title and bill of sale before the buyer rides away.
Montana lien release procedure
- Obtain Form MV21 from the Montana DOJ Motor Vehicles Division or the lienholder.
- Lienholder completes and signs MV21 releasing the lien.
- Submit MV21 with the existing title and title application at a county courthouse.
- Pay the title fee and receive a clean Montana title.

How long do I have to file a release of liability in Montana?▾

Do I owe Montana sales tax on the motorcycle I just sold?▾

Does Montana require a notary on the motorcycle bill of sale?▾
No. Montana does not require notarization for a private motorcycle bill of sale. A signed bill of sale with both parties' full names, addresses, signatures, and the date is sufficient for Montana DMV.
How does the buyer register the motorcycle in Montana?▾
The buyer brings the signed bill of sale and endorsed title to Montana DMV, pays the title fee (~$12) plus any applicable use tax, and receives a new Montana title in their name. Transfer must be completed within 40 days of the sale date.
Where is the VIN on a motorcycle?▾
The 17-character VIN on a motorcycle is stamped on the frame near the steering head (headstock). It is also stamped on the engine case in some makes. Confirm the VIN on the frame matches the title and bill of sale before the buyer rides away — a mismatch will block the title transfer at the DMV.
Is motorcycle title transfer different from a car title transfer?▾
The DMV process is the same — bill of sale + signed title + odometer disclosure. Some states have separate motorcycle title forms or lower registration fees. The release-of-liability filing is identical to cars and protects you the same way.
