How to Register Motorcycles, RVs, and Trailers

Motorcycle registration

Motorcycles must be titled and registered the same as other motor vehicles, except they do not require an emissions test and fees & taxes are likely to be less.
Low-power scooters must be registered directly with the state by completing this Registration Application. More info (including definition of a low-power scooter) on the state’s DMV page.
Dirt bikes (or off-road bikes) are not considered motor vehicles by the state, but still need to be registered with Colorado Parks and Recreation

RVs and Motor Homes

Colorado law requires motor homes and RVs to be titled and registered the same way as other motor vehicles.
Taxes and Fees are likely to cost more due to the heavier weight of these vehicles.
A weight slip will be required for out-of-state vehicles if the empty weight is over 4,500 pounds and is not listed on the title.

Trailer Registration

Colorado law requires that all trailers be titled, registered, and plated.
Trailers from Colorado: Visit one of our offices and bring Secure & Verifiable ID, the Colorado title, and paperwork if purchased from a Colorado dealer.
Out-of-State or homemade/kit trailers: Visit our Trailer page for registration instructions.
