At the heart of the 2007 Zongshen SC125 scooter motorcycle, Zongshen utilizes a 125 cc (7.6 cu in) oil & air-cooled single cylinder, four-stroke layout. In factory specification, peak output is rated at 8 HP (5.8 kW) while maximum torque reaches 7.1 Nm (5.2 lb-ft), transferring power to the rear wheel through a automatic gearbox and belt final drive. With a specific output of 64 HP per liter, the engine character is indicating a tractable, stress-free state of tune focused on everyday usability and broad torque delivery.
On the scales, the SC125 measures 136.1 kg (300 lbs) wet (curb), translating to a power-to-weight ratio of 0.06 HP/kg (17.01 kg per horsepower). The 6.06-liter (1.6 US gal) fuel tank paired with a rated consumption of 2.76 L/100 km provides an estimated theoretical range of roughly 220 km (137 miles) between fill-ups, while factory top speed is listed at 113 km/h (70 mph).
