Yes, Yamaha historically produced two-stroke engine golf carts, most notably the Yamaha G1 model from the late 1970s to early 1980s. These gasoline-powered carts featured air-cooled 285-336cc two-stroke engines delivering 9-11 HP, designed for light-duty terrain. However, Yamaha transitioned to four-stroke engines in later models (G2 onward) to meet emissions regulations and improve torque efficiency. Vintage G1 units remain popular in collector markets for their mechanical simplicity and distinctive engine sound.
Yamaha G1 Golf Cart – A Timeless Classic
What technical specs defined Yamaha’s two-stroke golf carts?
The Yamaha G1 used a single-cylinder two-stroke engine with reed valve induction and chain final drive. Its 336cc powerplant produced 9.3 HP at 4,500 RPM, paired with a centrifugal clutch and 4-forward/1-reverse gearbox. Pro Tip: Mix oil at 1:50 ratio (2% oil) for proper lubrication – incorrect ratios cause piston seizures in these premix systems.
These carts weighed 350-400 lbs with a 35 mph governed top speed. The compact engine design allowed tight turning radii ideal for golf course paths. For example, the G1’s free-air cooling system eliminated radiators but required regular spark plug changes in dusty conditions. Practically speaking, their carbureted systems needed seasonal jetting adjustments for altitude changes. Transitioning to later models, Yamaha prioritized EPA-compliant four-stroke engines starting with the G2 in 1985.
How does the G1 compare to modern electric carts?
The G1’s gasoline-powered operation contrasts sharply with today’s lithium-ion electric models. While modern 72V systems deliver silent, emissions-free torque, two-stroke carts offer nostalgic mechanical engagement. Here’s a 2×3 comparison:
| Feature | Yamaha G1 (2-Stroke) | Modern Electric (e.g., ICON) |
|---|---|---|
| Power Source | 336cc Gasoline | 72V Lithium |
| Range | 90-120 km/tank | 80-110 km/charge |
| Maintenance | Weekly (spark plugs, oil) | Annual (battery checks) |
Though less eco-friendly, vintage two-stroke models like the G1 still outperform electrics in cold weather reliability. But how many clubs still permit gasoline carts given noise restrictions? Most courses now mandate electric fleets.

FAQs
Yes, retrofit kits replace the two-stroke engine with 5-7kW motors and 48-72V battery packs. However, frame modifications may be needed for lithium pack integration.
Are two-stroke golf carts street legal?
Rarely – most jurisdictions prohibit them due to noise and emissions. Some rural areas grandfather pre-1985 models if mufflers are upgraded.
