During the early 1960s, Harley-Davidson collaborated with Italy's Aermacchi to distribute mid-sized four-stroke single-cylinder bikes under the H-D name. This lineup expanded to include various two-stroke models, ranging from 65 cc engines to minibikes.
Although the larger single-cylinder models achieved moderate success, the era demanded a more contemporary approach.
The SS-250, part of a series of four mid-sized two-stroke single-cylinder motorcycles inspired by Yamaha and launched by Harley-Davidson in the 1970s, debuted in 1975 as the largest street-legal model in the lineup.
Models designed for both on- and off-road use were labeled with the SX prefix, with options available in 175-cc and 250-cc engine sizes.
During this period, the Environmental Protection Agency started expressing concerns about two-stroke motorcycles being significant contributors to environmental pollution.
In hindsight, the shift to two-stroke engines may not have been the most strategic decision, leading Harley-Davidson to discontinue all single-cylinder models after 1978.
