Engineered by Kymco for the sport motorcycle segment, the 2009 Kymco Pulsar 125 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 8,750 rpm while maximum torque reaches 9.2 Nm (6.8 lb-ft) at 8,500 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 250 rpm working window between peak torque (8,500 rpm) and peak power (8,750 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 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 1,270 mm (50 in) wheelbase engineered for quick, flickable steering geometry. The 16-liter (4.2 US gal) fuel tank supports practical everyday commuting and weekend road stints.
