At the heart of the 2008 Jianshe JS125T-C scooter motorcycle, Jianshe features a 125 cc (7.6 cu in) air-cooled single cylinder, four-stroke configuration. In factory specification, peak output is rated at 6 HP (4.4 kW) at 7,300 rpm while maximum torque reaches 8.3 Nm (6.1 lb-ft) at 6,000 rpm, transferring power to the rear wheel through a 5-speed gearbox. With a specific output of 48 HP per liter and a 1,300 rpm working window between peak torque (6,000 rpm) and peak power (7,300 rpm), the engine character is prioritizing low-RPM tractability, mechanical longevity and relaxed throttle response over peak redline numbers.
On the scales, the JS125T-C measures 111 kg (245 lbs) dry, translating to a power-to-weight ratio of 0.05 HP/kg (18.5 kg per horsepower). Rider ergonomics and chassis geometry center around a 755 mm (29.7 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 1,363 mm (53.7 in) wheelbase engineered for quick, flickable steering geometry. The 5.4-liter (1.4 US gal) fuel tank supports practical everyday commuting and weekend road stints.
