Built around Docker's scooter motorcycle platform, the 2023 Docker Alpha S50 pairs a 48 cc (2.9 cu in) air-cooled single cylinder, four-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 2.7 HP (2 kW), transferring power to the rear wheel through a 4-speed gearbox and chain final drive.
On the scales, the Alpha S50 measures 97 kg (214 lbs) wet (curb). Rider ergonomics and chassis geometry center around a 1,230 mm (48.4 in) wheelbase engineered for quick, flickable steering geometry. The 3.7-liter (1 US gal) fuel tank supports practical everyday commuting and weekend road stints.
