Engineered by Wk for the allround motorcycle segment, the 2021 Wk Colt 50 utilizes a 49.2 cc (3 cu in) air-cooled single cylinder, four-stroke layout. In factory specification, peak output is rated at 3 HP (2.2 kW) at 6,000 rpm while maximum torque reaches 3.4 Nm (2.5 lb-ft) at 6,000 rpm, transferring power to the rear wheel through a 4-speed gearbox and chain final drive. Internal engine geometry specifies a bore and stroke of 39.0 x 41.4 mm (1.5 x 1.6 inches).
Rider ergonomics and chassis geometry center around a 760 mm (29.9 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 1,210 mm (47.6 in) wheelbase engineered for quick, flickable steering geometry. The 12-liter (3.2 US gal) fuel tank supports practical everyday commuting and weekend road stints, while factory top speed is listed at 45 km/h (28 mph).
