At the heart of the 2008 Zongshen 125 - 30 custom - cruiser motorcycle, Zongshen pairs a 124.6 cc (7.6 cu in) air-cooled single cylinder, four-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 11.3 HP (8.2 kW) at 9,000 rpm while maximum torque reaches 8.6 Nm (6.3 lb-ft) at 7,500 rpm, transferring power to the rear wheel through a 5-speed gearbox and chain final drive. With a specific output of 90.7 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 125 - 30 measures 117 kg (258 lbs) dry, translating to a power-to-weight ratio of 0.1 HP/kg (10.35 kg per horsepower). Rider ergonomics and chassis geometry center around a 670 mm (26.4 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 1,390 mm (54.7 in) wheelbase engineered for quick, flickable steering geometry. The 8-liter (2.1 US gal) fuel tank paired with a rated consumption of 2.2 L/100 km provides an estimated theoretical range of roughly 364 km (226 miles) between fill-ups, while factory top speed is listed at 115 km/h (71 mph).
