Engineered by Thumpstar for the trial motorcycle segment, the 2024 Thumpstar TSN 250 utilizes a 250 cc (15.3 cu in) liquid-cooled single cylinder, two-stroke layout.
On the scales, the TSN 250 measures 113 kg (249 lbs) wet (curb). Rider ergonomics and chassis geometry center around a 940 mm (37 in) seat height — reflecting a long-travel chassis stance that favors ground clearance and off-pavement control, combined with a 1,481 mm (58.3 in) wheelbase engineered for balanced agility and highway composure. The 9.5-liter (2.5 US gal) fuel tank supports practical everyday commuting and weekend road stints, while factory top speed is listed at 120 km/h (75 mph).
