Built around Thumpstar's minibike, sport motorcycle platform, the 2020 Thumpstar TSB 70 pairs a 70 cc (4.3 cu in) single cylinder, four-stroke architecture with road-focused gearing.
On the scales, the TSB 70 measures 50 kg (110 lbs) dry. Rider ergonomics and chassis geometry center around a 607 mm (23.9 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 980 mm (38.6 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 70 km/h (43 mph).
