Built around Yamaha's allround motorcycle platform, the 1983 Yamaha DT 50 MX relies on a 50 cc (3.1 cu in) air-cooled single cylinder, two-stroke powerplant.
On the scales, the DT 50 MX measures 85 kg (187 lbs) wet (curb). Rider ergonomics and chassis geometry center around a 790 mm (31.1 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance. The 4.23-liter (1.1 US gal) fuel tank supports practical everyday commuting and weekend road stints, while factory top speed is listed at 105 km/h (65 mph).
Within MotoLibrary's Yamaha archive, this model family spans 3 indexed model years from 1981 to 1983, allowing buyers to track year-over-year changes in emissions tuning, weight and equipment.
