Positioned in WK's scooter motorcycle lineup, the 2017 WK VS50 utilizes a 49 cc (3 cu in) air-cooled single cylinder, four-stroke layout. In factory specification, peak output is rated at 3.2 HP (2.4 kW) at 7,500 rpm while maximum torque reaches 3.4 Nm (2.5 lb-ft) at 5,900 rpm, transferring power to the rear wheel through a automatic gearbox and belt final drive. Internal engine geometry specifies a bore and stroke of 39.0 x 41.4 mm (1.5 x 1.6 inches).
On the scales, the VS50 measures 94 kg (207 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. The 5-liter (1.3 US gal) fuel tank supports practical everyday commuting and weekend road stints.
