Responding to the scooter boom of the early 1980s, this is the highest grade of the Gemma series, which originally debuted as a 50 cm³ model. Its 125 cm³ air-cooled 4-stroke 1-cylinder engine was the largest Japanese-manufactured scooter engine of the time, and the only 4-stroke model in the Gemma series. The unique Suzuki Twin Dome Combustion Chamber (STDCC) helped this engine generate a high maximum power of 8.0 PS, stable torque, impressively low fuel consumption, and superb quietness. Matching the fashionable styling, the Gemma 125 was offered with either a 2-person double seat or a pillion seat for commercial applications.
