Free Missouri Motorcycle Bill of Sale
Missouri treats a motorcycle sale with more formality than most states: the title assignment must be NOTARIZED — both parties sign in front of a notary, a rule that applies to bikes exactly as it does to cars — and the bike needs a safety inspection on the biennial cycle (~$10 for motorcycles) before the buyer can register. The trade-off is a light tax load: 4.225% state plus local rates, and motorcycles are exempt from the St. Louis-area emissions program that catches cars. The buyer files form DOR-108 at a license office within 30 days and needs the Class M endorsement to put the new bike on the road legally.

Missouri Motorcycle Sale — Step-by-Step Checklist
- Verify the frame VIN and engine serial against the Missouri title before paying.
- Complete the bill of sale with VIN, engine serial, odometer, sale price, date, and both signatures.
- Do NOT sign the title at the kitchen table — Missouri requires the title assignment signed before a NOTARY, so meet at a bank or UPS store and sign there.
- Check the safety inspection status: Missouri motorcycles need the biennial inspection (~$10) — a current certificate saves the buyer a stop.
- Buyer files form DOR-108 at any Missouri license office within 30 days.
- Buyer pays the 4.225% state tax plus local rates (combined figures vary by address) and the title fee.
- Buyer: hold the Class M endorsement before riding — the title transfers without it, but road-legal riding doesn't.
Common Pitfalls
- Signing the title before reaching the notary — a pre-signed Missouri title assignment is the classic transfer-killer; the notary must witness the signatures.
- Assuming bikes skip all inspections — motorcycles dodge the St. Louis emissions test but still ride the biennial safety inspection cycle.
- Budgeting only 4.225% — local sales taxes stack on top, and the combined rate varies meaningfully across Missouri.
- Missing the 30-day DOR-108 window — late penalties accrue on top of the tax.
Pro Tip
Missouri motorcycles: sign the title at the notary (never before), pass the ~$10 biennial safety check, file DOR-108 within 30 days at 4.225% plus local — and skip the emissions line entirely.
