Engineered by Bennche for the allround motorcycle segment, the 2020 Bennche JS150U utilizes a 149.6 cc (9.1 cu in) air-cooled single cylinder, four-stroke layout. In factory specification, peak output is rated at 74 HP (54 kW), transferring power to the rear wheel through a automatic gearbox and chain final drive. With a specific output of 494.7 HP per liter, the engine character is placing it firmly in high-revving supersport territory where top-end breathing dominates.
On the scales, the JS150U measures 93 kg (205 lbs) dry, translating to a power-to-weight ratio of 0.8 HP/kg (1.26 kg per horsepower). Rider ergonomics and chassis geometry center around a 622 mm (24.5 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 1,181 mm (46.5 in) wheelbase engineered for quick, flickable steering geometry. The 1.89-liter (0.5 US gal) fuel tank supports practical everyday commuting and weekend road stints, while factory top speed is listed at 39 km/h (24 mph).
