Built around Kymco's sport motorcycle platform, the 2012 Kymco Pulsar 125 LX features a 124.1 cc (7.6 cu in) air-cooled single cylinder, four-stroke configuration. In factory specification, peak output is rated at 10.1 HP (7.3 kW) at 8,500 rpm while maximum torque reaches 9.2 Nm (6.8 lb-ft) at 7,000 rpm, transferring power to the rear wheel through a 5-speed gearbox and chain final drive. With a specific output of 81.4 HP per liter and a 1,500 rpm working window between peak torque (7,000 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 Pulsar 125 LX measures 117 kg (258 lbs) dry, translating to a power-to-weight ratio of 0.09 HP/kg (11.58 kg per horsepower). Rider ergonomics and chassis geometry center around a 780 mm (30.7 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,270 mm (50 in) wheelbase engineered for quick, flickable steering geometry. The 16-liter (4.2 US gal) fuel tank paired with a rated consumption of 2.35 L/100 km provides an estimated theoretical range of roughly 681 km (423 miles) between fill-ups, while factory top speed is listed at 105 km/h (65 mph).
