Engineered by Keeway for the scooter motorcycle segment, the 2011 Keeway RY8 50 relies on a 49.3 cc (3 cu in) single cylinder, four-stroke powerplant. In factory specification, peak output is rated at 4.4 HP (3.2 kW) at 7,500 rpm while maximum torque reaches 4 Nm (3 lb-ft) at 6,500 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 RY8 50 measures 90 kg (198 lbs) dry. Rider ergonomics and chassis geometry center around a 1,270 mm (50 in) wheelbase engineered for quick, flickable steering geometry. The 4.8-liter (1.3 US gal) fuel tank supports practical everyday commuting and weekend road stints.
