Engineered by Kymco for the scooter motorcycle segment, the 2012 Kymco RS 50 features a 49 cc (3 cu in) air-cooled single cylinder, four-stroke configuration. In factory specification, peak output is rated at 3.5 HP (2.5 kW) at 7,500 rpm while maximum torque reaches 3.2 Nm (2.4 lb-ft) at 4,000 rpm, transferring power to the rear wheel through a 4-speed gearbox and shaft drive (cardan) final drive. Internal engine geometry specifies a bore and stroke of 39.0 x 41.0 mm (1.5 x 1.6 inches) with a 8.0:1 compression ratio.
On the scales, the RS 50 measures 95 kg (209 lbs) dry. Rider ergonomics and chassis geometry center around a 780 mm (30.7 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,325 mm (52.2 in) wheelbase engineered for quick, flickable steering geometry. The 3.5-liter (0.9 US gal) fuel tank supports practical everyday commuting and weekend road stints, while factory top speed is listed at 48 km/h (30 mph).
