Yes, you need a motorcycle license to ride a grom on public roads in all U.S. states
A grom is a small-displacement motorcycle, typically 125cc or under, made by brands like Honda, Yamaha, and Kawasaki. Despite their size, groms are classified as motorcycles by law, not mopeds or scooters. That means you cannot legally ride one on a street, highway, or any public road without a valid motorcycle license or endorsement on your driver's license.
The specific license you need depends on your state and the grom's engine size. Most states require a full motorcycle license (Class M or similar) for any bike over 50cc. Some states allow a moped or motorized bicycle license for bikes under 50cc, but groms typically exceed that threshold. A few states offer a separate endorsement for small-displacement bikes, but you still need a base driver's license plus that endorsement.
Private property is the only place where a license is not required. You can ride a grom on your own land, a closed track, or a private parking lot without any license. Many riders use groms for off-road riding or track days, where licensing rules differ or do not explore.
Key Takeaways
- Groms are legally classified as motorcycles, so you need a motorcycle license or endorsement to ride one on public roads in every state.
- Most states require a full Class M motorcycle license for bikes over 50cc, and groms typically fall into this category.
- You can ride a grom without a license only on private property, closed tracks, or off-road terrain.
- The process to get a motorcycle license usually involves passing a written test, a riding skills test, and sometimes a safety course.
- Some states waive the riding test if you complete an approved motorcycle safety course.
How grom engine size affects licensing requirements
Engine displacement, measured in cubic centimeters (cc), is what determines whether you need a motorcycle license or a lighter endorsement. A grom under 50cc might be classified as a moped or motorized bicycle in your state, which sometimes requires only a moped license or a straightforward written test. However, most groms sold in the U.S. are 125cc, which puts them squarely in motorcycle territory.
A 125cc grom requires a full motorcycle license in all 50 states. Some states have a separate "motorcycle endorsement for small bikes" or similar category, but you still need a base driver's license plus that endorsement. A few states, like California, allow you to take a different test for bikes under 250cc, but the license is still a motorcycle license, not a moped license.
If you are considering a grom and do not yet have a motorcycle license, check your state's Department of Motor Vehicles website to confirm the exact classification and test requirements for the specific engine size you want to ride.
What the motorcycle license test covers
Getting a motorcycle license involves three parts in most states: a written knowledge test, a riding skills test, and sometimes a safety course. The written test covers traffic laws, motorcycle-specific rules, hazard recognition, and basic maintenance. You study a motorcycle handbook provided by your state's DMV, and the test is usually 25 to 50 questions with a passing score of 80 percent or higher.
The riding skills test takes place on a closed course, not public roads. You demonstrate basic control: starting, stopping, turning, swerving, and figure-eight maneuvers. The test is typically 10 to 15 minutes long. You must bring your own motorcycle or use one provided by a testing facility. Many riders fail the riding test on their first attempt because they underestimate how much control a motorcycle requires at low speeds.
Some states waive the riding test if you complete an approved motorcycle safety course, such as the Motorcycle Safety Foundation (MSF) Basic Rider Course. This course is two or three days long, costs between $150 and $300, and includes classroom instruction and hands-on riding. Many riders choose this route because it teaches skills before the test and removes the pressure of a single riding exam.
State-by-state differences in motorcycle licensing
Licensing rules vary by state, so you cannot assume your neighbor's process will match yours. Some states have a single motorcycle license class; others have separate classes for different engine sizes or bike types. A few states allow you to get a motorcycle endorsement on your regular driver's license without taking a separate test if you complete a safety course.
California, for example, requires a separate written test and riding test for motorcycles, and you cannot use a safety course to waive the riding portion. Texas allows you to waive the riding test with an MSF course completion card. New York requires a written test and a riding test, but the riding test can be waived if you hold a valid motorcycle license from another state.
The cost of a motorcycle license also varies. Written and riding tests are usually free or cost $10 to $30 total. A safety course costs $150 to $300. Your state's DMV website lists the exact requirements, fees, and testing locations in your area. Many states also allow you to schedule tests online.
Riding a grom without a license: penalties and risks
Riding a grom on a public road without a motorcycle license is illegal and carries real consequences. A first offense typically results in a fine of $100 to $500, depending on your state. A second offense can mean a larger fine, points on your driving record, or both. In some states, riding without a license can result in your vehicle being impounded.
Beyond legal penalties, riding without a license means you have no formal training in motorcycle safety. Groms are small and light, which makes them feel straightforward to handle, but they still require balance, throttle control, and awareness of road hazards. Riders without training are more likely to crash, and a crash on a grom can still cause serious injury or death.
Insurance is another issue. If you cause an accident while riding without a license, your insurance will likely deny your claim. You would be personally liable for all damages and medical costs. Even if you are not at fault, riding without a license complicates the claims process and may result in your policy being cancelled.
How to get a motorcycle license for a grom
The fastest path is usually a motorcycle safety course. Find an MSF-certified course in your area through the MSF website or your state's DMV. Courses are offered year-round in most states, with weekend and evening options available. You bring your own motorcycle or use one provided by the course. After you pass, you receive a completion card that you take to the DMV to get your license without a riding test.
If you prefer to test without a course, visit your state's DMV website to find testing locations and schedule a written test. Once you pass the written test, you schedule a riding test at a separate appointment. You must bring your own motorcycle, proof of insurance, and a valid ID. The riding test is usually available within two weeks of your written test passing.
Before you test, practice on your grom in a parking lot or empty lot. Work on slow-speed control, smooth acceleration, and stopping in a straight line. These are the skills the riding test focuses on. Many riders spend a few weeks practicing before attempting the test, which significantly improves their pass rate.
Alternatives if you cannot get a motorcycle license yet
If you are under the minimum age for a motorcycle license in your state (usually 16 or 18), you may be able to get a learner's permit or a restricted license. A learner's permit lets you ride with supervision, usually a licensed adult on a separate motorcycle. A restricted license limits where and when you can ride, often prohibiting night riding or highway use.
Some states offer a youth motorcycle license for riders under 18 with a smaller engine displacement limit, such as 250cc or 500cc. This is a full license, not a permit, but it restricts the bikes you can legally ride. Once you turn 18 or reach a certain age, you can upgrade to an unrestricted motorcycle license without retesting.
If you want to ride a grom but are not yet old enough for a motorcycle license, riding on private property is your only legal option. Many riders use this time to practice on a grom in a parking lot or on a closed course, building skills before they test for a license.
Frequently Asked Questions
Can I ride a grom with just a regular driver's license?
No. A regular driver's license does not cover motorcycles. You need a separate motorcycle license or endorsement, even for a small grom. The only exception is if your state allows moped licenses for bikes under 50cc, but most groms are 125cc and require a motorcycle license.
What if I ride a grom on private land without a license?
You can ride on private property without a license. This includes your own land, a friend's property with permission, closed tracks, and off-road trails on private land. You cannot ride on any public road, parking lot, or street without a license, even if traffic is light.
Do I need a motorcycle license if I ride a grom only on a track?
No. Track days and closed courses do not require a motorcycle license. You can ride a grom at a track day or racing school without a street license. However, you still need insurance and a helmet, and you must follow the track's rules.
How long does it take to get a motorcycle license?
A safety course takes two to three days and results in a license within a week. If you test without a course, the written test is when ready, and the riding test is usually scheduled within two weeks. The DMV processes your license within one to two weeks after you pass.
Can I use a motorcycle license from another state to ride a grom in my state?
Yes. A valid motorcycle license from any U.S. state is recognized in all other states. You can ride a grom with an out-of-state motorcycle license. If you move to a new state, you can transfer your license to that state's DMV, usually without retesting.
