Best 300cc Scooters in 2026: Prices, Top Speed & Models Compared
Shopping for a 300cc scooter in the United States? Start with three genuine U.S.-market choices: the Yamaha XMAX (292cc), Vespa GTS 310 (310cc), and KYMCO Downtown GT 350i (321cc). All are automatic scooters; each suits a different kind of ride.
300cc scooter comparison: U.S. models and real engine sizes
| Model | Actual engine | 2026 starting MSRP | Weight / seat height | Brakes | U.S. status |

| Vespa GTS 310 | 310cc | $7,999 | Check U.S. dealer specification / approximately 31.1 in published seat height | ABS, traction control | Current new model |
| KYMCO Downtown GT 350i | 321cc | $6,599 | Confirm exact U.S. trim with dealer | ABS, traction control | Introduced to U.S. market 2026 |
| SYM Citycom S 300i | 278.3cc | Used pricing varies | Verify year and condition | Varies by market/year | Used-market possibility; not confirmed as new 2026 U.S. model |
MSRP is not the out-the-door price. Tax, title, dealer preparation, destination and optional accessories can add to the bill. Figures refer to published U.S. manufacturer information checked November 2026; check exact year and trim before purchasing.
1. Yamaha XMAX — best 300cc-class scooter for highway-oriented commuting
292cc · $6,399 base MSRP · 403 lb wet · 31.3-inch seat · ABS
For commuters who mix city streets, suburban arterial roads and highway stretches, the XMAX is our first model to compare. Its 292cc liquid-cooled engine and automatic CVT remove shifting from stop-and-go riding. Larger 15-inch front and 14-inch rear wheels, a tall screen, weather protection and underseat storage make it more of a practical maxi-scooter than a minimalist city runabout.
What stands out: predictable published specifications, wind protection, storage and a strong highway-oriented layout. Before buying: at 403 pounds ready to ride and 31.3 inches at the seat, it may feel taller and heavier than a 150cc urban scooter. Try parking maneuvers and flat-footing it in person. Yamaha lists a $650 destination charge in addition to MSRP, before other dealer costs.

310cc · $7,999 base MSRP · ABS and traction control
The GTS 310 appeals to buyers who want the recognizable steel-body Vespa design without staying in the 150cc class. Its 310cc single-cylinder automatic drivetrain, dual disc brakes, ABS and traction control make it a substantial modern scooter with a distinctly different look from the Yamaha.
What stands out: classic design, premium finish and city maneuverability. Trade-offs: a higher purchase price, smaller wheels than the XMAX, and potentially expensive body repairs. For frequent long-distance highway use, compare wind protection and your seated position with the XMAX rather than assuming the larger engine automatically makes it the better tourer.

3. KYMCO Downtown GT 350i — a larger-class alternative
321cc · $6,599 starting MSRP · ABS + traction control
Despite the “350i” badge, the Downtown GT actually displaces 321cc. KYMCO USA introduced the model in May 2026, positioning it for commuting and longer rides. Equipment announced for the U.S. includes ABS, traction control, keyless ignition and a seven-inch color display.
Why consider it: modern features and a more powerful class at a starting MSRP close to the XMAX. Before buying: check whether a local workshop supports the exact model, what replacement parts cost, and the dealer's full quote. A desirable feature list is not a substitute for nearby service support.

278.3cc · historical U.S. listing · used availability varies
The Citycom S 300i is worth knowing about if you want a 300cc-class commuter on a tighter budget. Older U.S.-distributor material lists a 278.3cc engine and 16-inch wheels. That does not establish availability as a new 2026 U.S. scooter. Treat listings as individual used-vehicle opportunities and verify the VIN, year, title, service records, parts access and local mechanic support.
Used scooters can be excellent value when maintenance history is documented. An inexpensive neglected example can quickly cost more than a properly serviced one.
How fast is a 300cc scooter?
A 300cc-class scooter can be suitable for highway riding, but top speed is not fixed by engine displacement alone. Rider weight, wind, incline, aerodynamic shape, load and tire condition all matter. Online speed claims are frequently drawn from different markets and speedometer readings rather than comparable testing.
Rather than promising a single mph number, check the exact model and its ability to sustain your local traffic speed with some margin for safe merging. On faster interstates, compare wind protection, passing response, braking performance and whether you will carry a passenger. A scooter that touches a number briefly may not be pleasant at that speed for an hour.
Yamaha XMAX vs. Vespa GTS 310 vs. KYMCO Downtown GT
Choose the XMAX if your priorities are wind protection, storage and a highway-focused commuter layout. Choose the GTS 310 if premium Vespa design and compact urban use matter more to you than maximum practicality per dollar. Investigate the Downtown GT if you want its larger 321cc engine and modern equipment, especially when you have a nearby KYMCO service dealer.
None is automatically the best for everyone. Sit on the models, check insurance quotes and assess parking weight before paying a deposit.
What does a 300cc scooter really cost to own?
Start with the listed MSRP, then request a written out-the-door quote showing destination, assembly/preparation, documentary charges, tax, title and registration. Budget separately for insurance, helmet and riding gear, tires, drive-belt/CVT service, brake pads and routine fluids.
Fuel economy can be economical compared with a car, but maintenance is model-specific. Ask how many miles the service schedule allows between belt and tire changes, what each service costs locally, and whether the shop stocks common consumables. Our scooter cost guide explains the main categories of purchase and ownership costs.
New vs. used 300cc scooters: buying checklist
- Match the VIN, registration and title; investigate liens and salvage history.
- Start a cold engine and watch for smoke, persistent warning lights and unusual transmission noise.
- Look for CVT belt and roller service records, not just engine oil changes.
- Inspect tire age, wear, wheel damage, suspension leaks and brake rotor condition.
- Look for signs of drops and damaged plastic or steel body panels.
- Confirm both keys, immobilizer operation, ABS warning-light behavior and electrical functions.
- Test storage, seat latch and windshield adjustment where equipped.
- Ask a nearby scooter mechanic for a pre-purchase inspection.
Is there a Honda 300cc scooter in the U.S.?
Honda's current mainstream U.S. scooter lineup does not offer a direct new 300cc counterpart to the XMAX or GTS 310. Honda has sold larger scooters in other markets, including Forza models, and the older Honda Reflex and Helix are relevant used alternatives. Don't assume an overseas Honda listing is a new U.S.-dealer model. For used 250cc Honda options, see the 250cc scooter guide.
What about 300cc scooter trikes?
Three-wheel scooters, conversion kits and motor trikes appear under this search phrase, but they are not direct equivalents to the two-wheel Yamaha, Vespa and KYMCO models here. Confirm whether a listing is a factory-engineered three-wheeler or an aftermarket conversion, and check the relevant state motorcycle-license requirements before purchasing.
