Free Colorado Motorcycle Bill of Sale
Colorado's DMV lists motorcycles and autocycles as exempt from emissions testing — even on the Front Range where cars test biennially. The rest of a Colorado bike transfer is the state's standard county machinery: a bill of sale (DR 2173 or a written equivalent), a generous 60-day window at the county clerk and recorder, and a tax bill built from your ADDRESS — 2.9% state base plus local rates that push past 8% in metro Denver. Two Colorado quirks deserve attention: a title held electronically by a lender must be paid off and released before a paper title can be signed, and the annual Specific Ownership Tax returns with every registration.

Colorado Motorcycle Sale — Step-by-Step Checklist
- Verify the frame VIN against the Colorado title before paying.
- Complete a bill of sale (DR 2173 or a written equivalent) with VIN, year, make, model, odometer, real price, date, and both signatures.
- Seller signs the paper title over — if a lender still holds the title electronically, the loan must be paid off first; ask BEFORE meeting.
- Buyer files at the county clerk and recorder within 60 days.
- Buyer pays 2.9% state tax plus the local rates of their home address (past 8% in metro Denver) and fees.
- Budget the annual Specific Ownership Tax — Colorado's ad valorem charge renews with every registration and declines as the bike ages.
- No emissions stop, ever — and carry Colorado's motorcycle endorsement before riding.
Common Pitfalls
- Meeting the seller without asking about a lien — a title held electronically by a lender can't be signed over until the loan is paid and a paper title is issued.
- Quoting the 2.9% as the tax bill — the buyer's local rates stack on top and vary block by block across the metro counties.
- Forgetting the Specific Ownership Tax — the purchase tax is once, but SOT returns annually with registration.
- Coasting on the 60 days — generous, but day 61 brings late fees.
Pro Tip
Colorado motorcycles: title and register at the county clerk within 60 days, address-based tax at purchase, SOT annually after — and the emissions line is for the four-wheeled.
