In 1962, Suzuki won the manufacturers’ title in the 50 cc class of the Road Racing World Championship. In 1963, riding a Suzuki, Mitsuo Ito became the first Japanese rider to win the Isle of Man TT Races in the 50 cc class. In the same year, Suzuki took the manufacturers’ titles in both the 50 and 125 cc classes. These successes demonstrate the recognition achieved by Suzuki’s 2-stroke engine technologies on the world stage. The Sport 80K11 is the sister model of the Suzuki Sport 50 that debuted in the same year. Based on the Selped 80K, the intention at the design stage was to develop a model that could be ridden easily by anyone. Features include functional pipe handlebars, telescopic forks, naked style shock-absorbing springs, a metallic front fender, a muffler positioned high up on the side of the body, and a rotary 4-speed automatic transmission. The top speed of 95 km/h and maximum horsepower of 7.3 PS both exceed the performance of the base Selped 80K model. It also achieves excellent steady state fuel economy of 75 km/L*.

The A90 is the sister model of the A70 and features a so-called V-bone frame that emphasizes sportiness through a separate rear fender. Its 2-stroke 90 cm³ rotary disc valve engine (bore × stroke dimensions: 47 × 50 mm) is equipped with the Cylinder Crank Injection (CCI) system. The model has a top speed of 100 km/h and generates maximum horsepower of 8.4 PS.

With every model in the Suzuki A series proving to be extremely popular, the Sport AS90 was designed in response to a predicted shift in demand toward sporty models. Therefore, a deluxe version of the existing 90 cm³ model was developed with the aim of appealing to a wider user base. The AS90 combines a vivid candy-red body color with chrome plating on the front and rear fenders and the chain case. Metallic seat ends were also adopted.

The AC90 debuted at the same time as the AS90. Although developed with similar aims, the AC90 utilizes the powerful engine from the A90 for higher performance on rough roads. Various measures were adopted to realize this purpose, including the installation of a muffler positioned high up on the side of the body, the adoption of a wider 2.75-inch rear tire for improved hill climbing performance, and a minimum ground clearance of 205 mm, 50 mm higher than the AS90. The body color is a vivid candy red and chrome plating is adopted on the front and rear fenders and the chain case. Other features include a newly designed side stand and a fixed step.
