At the heart of the 1982 Yamaha CA50M scooter motorcycle, Yamaha pairs a 49 cc (3 cu in) air-cooled single cylinder, two-stroke architecture with road-focused gearing. Internal engine geometry specifies a bore and stroke of 40.0 x 39.2 mm (1.6 x 1.5 inches) with a 7.0:1 compression ratio.
On the scales, the CA50M measures 63 kg (139 lbs) wet (curb). Rider ergonomics and chassis geometry center around a 1,130 mm (44.5 in) wheelbase engineered for quick, flickable steering geometry. The 3.8-liter (1 US gal) fuel tank supports practical everyday commuting and weekend road stints, while factory top speed is listed at 72 km/h (45 mph).
