The M80 is a commercial model that realizes a superb balance between performance and rider friendliness by combining an easy-to-mount V-shaped underbone frame with a powerful and well-received 80 cm³ 2-stroke engine. This newly designed engine generates a horsepower to weight ratio of 11.7 kg, 1 kg better than other models. Engineered to emphasize low-speed performance, it delivers impressively gutsy torque in the low- and mid-rpm ranges and excellent riding capabilities at low speeds even in top gear. The materials of the new frame that underpins this performance have a thickness of only 1.4 mm, realizing a lightweight 70 kg chassis. Every aspect of this model was designed specifically for the M80, including the large-capacity 5.8-liter fuel tank.

The U70 is a rider-friendly model that features a 70 cm³ 2-stroke air-cooled 1-cylinder engine equipped with Suzuki’s unique Cylinder Crank Injection (CCI) system mounted on a curvaceous body designed to evoke the image of a swan floating on the surface of a lake. This model enables tough performance and effortless handling by pairing this engine, which generates maximum horsepower of 6 PS, with a centrifugal clutch and rotary 3-speed automatic transmission. It also achieves excellent fuel economy of 90 km/L (50 km/h steady state fuel economy*). Other features include a front-opening seat and a fuel tank mounted on the right-hand side.

The Super Free 80 is equipped with an 80 cm³ 2-stroke 1-cylinder rotary valve engine that delivers excellent power at low rpms. A 3-speed transmission with a centrifugal clutch allows the engine to be started simply by opening the throttle. Designed with simple operation that can be swiftly mastered even by beginners, this is a commercial model that is fun- and easy-to-ride by anyone. It also features an automatic negative pressure fuel cock that shuts off when the engine is stopped to prevent fuel overflow from the carburetor, which was a common concern of the time.

The Super Free 70 combines the chassis of the Super Free 50 with a newly designed 70 cm³ engine that achieves increased power and performance. A reed valve intake system was adopted to increase power at low rpms. Aside from the thickness of the frame, the chassis and electrical parts are the same as those on the Super Free 50.

The Birdie 70 pairs a 70 cm³ 2-stroke reed valve engine with a centrifugal clutch and rotary 3-speed automatic transmission. The models in the Birdie lineup are the first motorcycles to feature a fuel lamp that shows the gas level as standard equipment. The Birdie 70 lineup includes the commercial L model that is designed to carry heavy loads. Its features include three-way adjustable rear shock absorbers, a large-diameter rear tire, strong side stand, and bag hook. A model change in 1974 resulted in the debut of the 2-stroke 80 cm³ FR80.

The Birdie 80 is equipped with a reed valve 80 cm³ 2-stroke 1-cylinder engine designed to deliver torqueful output in the low- and mid-rpm ranges. Because of the quietness of its engine, the model is suited for riding on city streets, while still delivering impressive hill-climbing performance. A centrifugal clutch and rotary 3-speed automatic transmission eliminate the difficulty of clutch operations and realize an easy and comfortable ride for inexperienced riders. User-friendliness is further enhanced by features including a fuel gauge located at the rear of the seat that shows the gasoline level at a glance, a large-capacity 1.2-liter oil tank with a gauge that enables longer rides, and a primary kickstarter that can start the bike regardless of the gear position.
