Engineered by Thumpstar for the minibike, sport motorcycle segment, the 2020 Thumpstar TSK 50 utilizes a 50 cc (3.1 cu in) single cylinder, four-stroke layout.
On the scales, the TSK 50 measures 50 kg (110 lbs) dry. Rider ergonomics and chassis geometry center around a 570 mm (22.4 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 920 mm (36.2 in) wheelbase engineered for quick, flickable steering geometry. The 3-liter (0.8 US gal) fuel tank supports practical everyday commuting and weekend road stints, while factory top speed is listed at 45 km/h (28 mph).
