Exports of motorcycles to developing countries increased dramatically during the 1970s, consistent with the growth of Southeast Asia's economies. Consumers in that region wanted practical motorcycles that could handle multiple passengers and overloading.
In order to meet the growing needs of this region, Honda exported the CS90 model with four-cycle OHC in January 1968, and then the CB100 in September 1969. In contrast, the company's competitors were exporting two-stroke, 100-cc models. Due to a lack of proper maintenance-a condition unique to that part of the world-Honda was losing ground to other manufacturers. In response, Honda developed a model featuring its new OHV engine, exporting it as the S110 in March 1973. The real problem, however, was not so easily solved.
