Built around Wk's scooter motorcycle platform, the 2021 Wk TTR 50 utilizes a 49.2 cc (3 cu in) air-cooled single cylinder, four-stroke layout. In factory specification, peak output is rated at 2.8 HP (2.1 kW) at 7,500 rpm while maximum torque reaches 3.4 Nm (2.5 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 39.0 x 41.4 mm (1.5 x 1.6 inches).
Rider ergonomics and chassis geometry center around a 730 mm (28.7 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 1,280 mm (50.4 in) wheelbase engineered for quick, flickable steering geometry. The 3.9-liter (1 US gal) fuel tank paired with a rated consumption of 1.81 L/100 km provides an estimated theoretical range of roughly 215 km (134 miles) between fill-ups, while factory top speed is listed at 45 km/h (28 mph).
