Off-Road Use: Registration Requirements
In Illinois, dirt bikes used exclusively off-road are not required to be registered with the Illinois Secretary of State. However, to ride on designated off-highway vehicle (OHV) trails, riders must obtain an OHV Usage Stamp from the Illinois Department of Natural Resources (IDNR).
OHV Usage Stamp Details:
- Requirement: All off-highway motorcycles (OHMs) operated on public lands must display a valid OHV Usage Stamp.
- Cost: The annual OHV Usage Stamp fee is $15.00, plus a $0.50 issuance fee to the point-of-sale vendor.
- Expiration: The OHV Usage Stamp expires on March 31 each year.
- Exemptions: Certain vehicles, such as those used for production agriculture or by qualifying hunters with disabilities, may be exempt from this requirement.
Title Requirements:
- Certificate of Title: All-terrain vehicles and off-highway motorcycles purchased on or after January 1, 1998, must apply for a $30 certificate of title. Machines used only for production agriculture need only pay $13.
Helmet and Eye Protection:
- Under 18: Operators and passengers under 18 are required to wear a DOT-approved helmet when operating or riding on a motorcycle.
- All Riders: Eye protection is recommended for all riders, regardless of age.
Age Restrictions:
- Under 16: Individuals under 16 years of age are prohibited from operating adult-sized ATVs or off-highway motorcycles on public lands.
Operation on Public Roads:
- Operating dirt bikes on public streets, roads, or highways is prohibited unless the bike has been modified to meet street-legal requirements and is properly registered and insured.
Lighting Requirements:
- If operating during low-light conditions, the dirt bike must be equipped with a functioning headlamp and taillamp.

Street Use: Converting a Dirt Bike to Street-Legal
Converting a dirt bike to be street-legal in Illinois is challenging due to state regulations. Illinois does not allow the registration of off-road motorcycles for street use if the title or VIN designates them as off-road only. However, there are alternative methods:
Alternative Registration Methods:
- Out-of-State Registration:
- Some riders choose to register their dirt bikes in states with more lenient laws, such as South Dakota or Vermont, and then transfer the registration to Illinois. This process may involve additional steps and fees.

- If the dirt bike’s MCO does not specify “off-road use only,” it may be possible to register it as a street-legal motorcycle in Illinois. This typically applies to dual-sport motorcycles designed for both on-road and off-road use.
