The M-50 Sport, a one-year-only production model, used a longer, racing-style , rubber-mounted 2.5 gallon ga tank and a two up saddle to achieve a sportier look. Its 50cc two-stroke single-cylinder engine delivered 3.5 horsepower. It weighed 112.5 pounds. The company manufactured and imported about 10,500 of these motorbikes in 1966. This Holiday Red and White example sold new for $275.
