Built around Znen's allround motorcycle platform, the 2014 Znen CG 125 utilizes a 124 cc (7.6 cu in) liquid-cooled single cylinder, four-stroke layout. In factory specification, peak output is rated at 10.7 HP (7.8 kW) at 8,500 rpm while maximum torque reaches 8.5 Nm (6.3 lb-ft) at 7,500 rpm, transferring power to the rear wheel through a 4-speed gearbox and chain final drive. With a specific output of 86.3 HP per liter and a 1,000 rpm working window between peak torque (7,500 rpm) and peak power (8,500 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 CG 125 measures 117 kg (258 lbs) dry, translating to a power-to-weight ratio of 0.09 HP/kg (10.93 kg per horsepower). Rider ergonomics and chassis geometry center around a 1,245 mm (49 in) wheelbase engineered for quick, flickable steering geometry. The 8.5-liter (2.2 US gal) fuel tank supports practical everyday commuting and weekend road stints, while factory top speed is listed at 105 km/h (65 mph).
