Wisconsin Laws: What You Need to Know
DirtLegal explains Wisconsin dirt bike rules, covering street-legal conversion, equipment requirements, and the best places to ride off-road.
Off-Road Use: Registration Requirements
In Wisconsin, dirt bikes are classified as off-highway motorcycles (OHMs) and must be registered with the Wisconsin Department of Natural Resources (DNR) to be legally operated on public lands and trails. Registration is valid for one year with a fee typically around $15 to $30 depending on the bike’s engine size. Proof of ownership such as a bill of sale and a completed application are required. Riders under 18 must complete an approved OHM safety course before operating on public lands._
All riders under 18 are required by law to wear helmets when operating OHMs. Helmets are strongly recommended for riders 18 and older.
