By some criteria, the type of motorcycle the Super Cub falls into is difficult to classify, landing somewhere between a scooter and a motorcycle, A plastic fairing ran from below the handlebars and under the footpegs, protecting the rider's legs from wind and road debris, as well as hiding the engine from view.
This design was like the full enclosure of a scooter, but unlike a scooter the engine and gearbox unit was not fixed to the rear axle. It moved the engine down and away from the seat, detaching the rear swingarm motion from the drivetrain for lower unsprung weight.
To this end American Honda Motor Company was founded in 1959.
The Honda Juno had been the first scooter to use polyester resin, or fiberglass reinforced plastic (FRP), bodywork, and even though production of the Juno had stopped in 1954 as a result of Honda Motor's financial and labor problems at the time, Fujisawa continued to encourage research in polyester resin casting techniques, and these efforts bore fruit for the Super Cub.
The following year Honda displayed a mockup to Fujisawa that finally matched what he had in mind, Fujisawa declaring the annual sales would be 30,000 per month, half again as many as the entire monthly two-wheeler market in Japan.The low compression ratio meant the engine could consume inexpensive and commonly available low octane fuel, as well as minimizing the effort to kick start the engine, making the extra weight and expense of an electric starter an unnecessary creature comfort.Though some of the many Super Cub variations came with both kick and electric start, the majority sold well without it.It also made engine cooling air flow more direct, and made it possible to fit larger wheels.The fuel tank was located under the hinged seat, which opened to reveal the fuel filler inlet.
