Positioned in Lexmoto's allround motorcycle lineup, the 2016 Lexmoto ZSB 125 relies on a 125 cc (7.6 cu in) air-cooled single cylinder, four-stroke powerplant. In factory specification, peak output is rated at 10.6 HP (7.7 kW) at 9,000 rpm while maximum torque reaches 9.5 Nm (7 lb-ft) at 7,000 rpm, transferring power to the rear wheel through a 5-speed gearbox and chain final drive. With a specific output of 84.8 HP per liter and a 2,000 rpm working window between peak torque (7,000 rpm) and peak power (9,000 rpm), the engine character is indicating a tractable, stress-free state of tune focused on everyday usability and broad torque delivery.
On the scales, the ZSB 125 measures 124.5 kg (274 lbs) dry, translating to a power-to-weight ratio of 0.09 HP/kg (11.75 kg per horsepower). Rider ergonomics and chassis geometry center around a 740 mm (29.1 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 1,295 mm (51 in) wheelbase engineered for quick, flickable steering geometry. The 13-liter (3.4 US gal) fuel tank supports practical everyday commuting and weekend road stints, while factory top speed is listed at 90 km/h (56 mph).
