Positioned in Kymco's custom - cruiser motorcycle lineup, the 2012 Kymco Zing II 125 relies on a 124.1 cc (7.6 cu in) air-cooled single cylinder, four-stroke powerplant. In factory specification, peak output is rated at 11.5 HP (8.4 kW) at 9,500 rpm while maximum torque reaches 9.3 Nm (6.9 lb-ft) at 7,750 rpm, transferring power to the rear wheel through a 5-speed gearbox. With a specific output of 92.7 HP per liter and a 1,750 rpm working window between peak torque (7,750 rpm) and peak power (9,500 rpm), the engine character is indicating a tractable, stress-free state of tune focused on everyday usability and broad torque delivery.
