The highest cc you can ride without a motorcycle license depends almost entirely on where you live.
Having zipped through New York traffic on a 50cc Vespa, tackled Arizona’s desert highways on a 125cc scooter, and navigated California’s strict registration laws, I’ve learned that engine size (cc) isn’t just about speed—it’s about legal loopholes, historical quirks, and very different state rules. Let’s break it down.
The 50cc Benchmark
Most states use 50cc as the magic number for license-free riding, but why? Blame the 1970s. Back in 1974, the NHTSA relaxed safety standards for mopeds, flooding the U.S. market with these pedal-assisted, low-power bikes. Lawmakers settled on 50cc as the cutoff to distinguish mopeds from motorcycles, arguing these pint-sized engines were safer for casual riders.
But here’s the catch: 50cc doesn’t mean “fast.” Most 50cc mopeds top out around 30 mph—enough for city errands but dicey on 45 mph roads. I learned this the hard way in Texas, hugging the shoulder while trucks roared past.
State-by-State Showdown: Where Can You Ride What?
This is where things get messy. While 50cc is a common baseline, states add their own twists. Here’s a snapshot of what I’ve encountered:
| State | Max CC Without Motorcycle License | Requirements |
|---|---|---|
| Alaska | Under 50cc | Basic driver’s license; teens 14-15 need a Class M2 license. Eye protection required. |
| Arizona | 50cc or under | Must register and insure mopeds. 25 mph speed cap. |
| California | Electric only (no gas engines) | Motorcycle license (M1/M2) required for all gas mopeds. Yes, even 50cc. |
| Arkansas | Under 250cc | Class M license needed, but no motorcycle endorsement for under 250cc. |
Wildcard Alert: Arkansas lets you ride up to 250cc without a motorcycle endorsement—great for backroad cruising. Meanwhile, California treats even a 50cc gas moped like a motorcycle, requiring a full license.

Real-World Riding
Let’s get practical. I’ve ridden everything from a rusty 50cc Honda in Alabama to a souped-up 150cc scooter in Florida. Here’s what engine size actually means for your ride:
- 50cc: Perfect for short trips. Gets ~100 mpg but struggles on hills. Merging into traffic? Pray for a tailwind.
- 125cc: My sweet spot. Hits 60 mph, handles highways, and still sips gas (~95 mpg). In states like Tennessee, that’ll still fly under the motorcycle license radar.
- 150cc+: Now you’re in motorcycle territory. Faster acceleration, but most states require endorsements.
Pro tip: Check your state’s speed limits too. Arizona bans mopeds from roads with speed limits over 35 mph, which is why I upgraded to a 125cc scooter there.
Electric Mopeds: The CC-Free Loophole
Electric mopeds and e-scooters don’t use cc—they’re measured in watts. States like Arizona classify e-scooters under 20 mph as “low-speed vehicles,” meaning no license is needed. California? They’ll slap a motorcycle license requirement on anything with a motor, electric or not.
I tested a 2000W e-moped in Colorado last summer—it hit 45 mph, and no license was required. Check your local laws because this gray area is evolving fast.
The Danger Zone: Modifying Your Moped
Tempted to tweak your 50cc to 80cc? Don’t. In Michigan, boosting your engine past 50cc reclassifies it as a motorcycle (Michigan Auto Law). I’ve seen buddies slapped with fines, impounded bikes, and even license suspensions for this. Plus, modified mopeds are liability magnets in accidents.
How to Ride Free (and Legal)
- Research Your State: Don’t assume 50cc = safe. California and Alabama are sticklers; Arkansas and Alaska are lenient.
- Consider Electric: E-mopeds often dodge cc-based laws.
- Prioritize Safety: Even if your state doesn’t require a license, take a riding course. Dropping a scooter at 30 mph still hurts.
Final Thoughts from the Saddle
Riding without a motorcycle license isn’t about loopholes—it’s about balancing practicality, legality, and that irreplaceable sense of freedom. Whether you’re buzzing through Brooklyn on a 50cc or exploring backroads on a 125cc, know your laws, respect your limits, and keep the rubber side down.
