Yamaha YCS1 180 Motorcycle - Street (1967-1969)

The Yamaha YCS1 180, produced from 1967 to 1969, was a popular two-stroke motorcycle known for its performance and innovative features for its era. This air-cooled parallel twin engine, displacing 180cc and delivering 20-21 horsepower, utilized Yamaha's Autolube oil injection system and twin Mikuni carburetors, paired with a five-speed transmission. During its production, the YCS1 was offered in several configurations. The standard YCS1, often called the "Bonanza," was the base model. A significant variant was the YCS1-C (or CS1C), a scrambler version featuring distinct visual elements like pearlescent white paint, braced handlebars, high pipes, and a bash plate. The "E" designation, as seen in YCS1E, indicated the inclusion of an electric starter, a notable innovation introduced in 1967 that became standard for the series. While the engine saw continuous minor refinements as part of the evolving CS series, these primary distinctions defined the models within the 1967-1969 range.
