Built around Jianshe's enduro - offroad motorcycle platform, the 2008 Jianshe JS125 GY4 relies on a 124 cc (7.6 cu in) air-cooled single cylinder, four-stroke powerplant. In factory specification, peak output is rated at 9.4 HP (6.8 kW) at 9,000 rpm while maximum torque reaches 8.8 Nm (6.5 lb-ft) at 7,500 rpm, transferring power to the rear wheel through a 5-speed gearbox. With a specific output of 75.8 HP per liter and a 1,500 rpm working window between peak torque (7,500 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 JS125 GY4 measures 110 kg (243 lbs) dry, translating to a power-to-weight ratio of 0.09 HP/kg (11.7 kg per horsepower). Rider ergonomics and chassis geometry center around a 875 mm (34.4 in) seat height — reflecting a long-travel chassis stance that favors ground clearance and off-pavement control, combined with a 1,170 mm (46.1 in) wheelbase engineered for quick, flickable steering geometry. The 6.5-liter (1.7 US gal) fuel tank supports practical everyday commuting and weekend road stints.
