Street-legal as sold once registered
Off-highway vehicle including a dirt bike (A.R.S. § 28-1171(6)) — street registration available under § 28-1177(C)
Arizona is one of the most electric-dirt-bike-friendly states in the country. A Sur-Ron-class bike is an off-highway vehicle (it exceeds the 750-watt e-bike limit), and to ride Arizona's vast public and state trust lands you need a $25/year OHV decal — plus, since January 1, 2025, a free one-time OHV safety course. What sets Arizona apart is a real street-legal pathway: unlike many states, Arizona will register a dirt bike 'street legal' for highway use if you equip it to motorcycle standards (lights, mirrors, and so on) and title and insure it. Between the huge legal riding areas and that on-road option, Arizona is a genuinely good place to own one. Riders under 18 must wear a DOT helmet.
Key points
- Classified as an off-highway vehicle, not an e-bike (exceeds 750W)
- $25/yr OHV decal required for public + state trust land; free OHV safety course required since Jan 1, 2025
- Real street-legal path — Arizona will register a properly-equipped dirt bike for highway use
- Vast public OHV riding (BLM, national forest, state trust land) — one of the best states to ride
- DOT helmet required for operators and passengers under 18
Where you can ride
Allowed

- Public highways — only if registered 'street legal' and equipped to motorcycle standards
- Private property
Prohibited
- Public highways without street-legal registration and motorcycle-standard equipment

Registration
RequiredArizona is the clearest path in the country, and it is deliberate. A.R.S. § 28-1171(6) names 'dirt bike' in the off-highway vehicle definition. § 28-1177(C) then provides that once you pay for a resident OHV user indicia, you may request motor vehicle registration if the machine meets the equipment requirements of Title 28, chapter 3, article 16, and on a signed affidavit 'the department shall register the vehicle for highway use' — with the registration fee waived. The final sentence reserves the provision for machines that did not already meet highway equipment requirements as produced, which is exactly this class. The affidavit is ADOT Form 96-0572. You also need a Class M licence (§ 28-3101(A)(6)), insurance, and a rearview mirror, seat and footrests (§ 28-964(B)). Since January 1, 2025 an OHV decal purchase also requires completing Arizona's safe and ethical riding course.
Helmet
Arizona requires a DOT-approved helmet for any operator or passenger under 18 on a motorcycle, ATV, or OHV (ARS §28-964, §28-1179). Riders 18 and older are not required to wear one but should.
License
No driver's license is needed to ride off-highway. To register the bike 'street legal' for highway use, it must be equipped to motorcycle standards, plus titled, registered, insured, and ridden with a motorcycle license.
Penalty risk
Riding on public or state trust land without a valid OHV decal, or on a public highway without street-legal registration, is subject to citation and fines.
Recent change
From January 1, 2025 an OHV decal purchase requires completing the 'Safe & Ethical Riding in Arizona' course. SB 1517 (ch. 221, Laws 2025, signed June 20, 2025) amended only § 28-2156, which applies to vehicles with four or more nonhighway tires and does not reach a two-wheeler.
