Engineered by Keeway for the scooter motorcycle segment, the 2021 Keeway RY6 50 pairs a 49.2 cc (3 cu in) air-cooled single cylinder, two-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 3.4 HP (2.4 kW) at 6,500 rpm while maximum torque reaches 3.7 Nm (2.7 lb-ft) at 6,000 rpm, transferring power to the rear wheel through a automatic gearbox and belt final drive. Internal engine geometry specifies a bore and stroke of 40.0 x 39.2 mm (1.6 x 1.5 inches) with a 6.9:1 compression ratio.
On the scales, the RY6 50 measures 88 kg (194 lbs) dry. Rider ergonomics and chassis geometry center around a 770 mm (30.3 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,270 mm (50 in) wheelbase engineered for quick, flickable steering geometry. The 6-liter (1.6 US gal) fuel tank supports practical everyday commuting and weekend road stints, while factory top speed is listed at 45 km/h (28 mph).
Within MotoLibrary's Keeway archive, this model family spans 2 indexed model years from 2011 to 2021, allowing buyers to track year-over-year changes in emissions tuning, weight and equipment.
