Built around LML's scooter motorcycle platform, the 2012 LML Star 4S 125 Classic features a 124.9 cc (7.6 cu in) air-cooled single cylinder, four-stroke configuration. In factory specification, peak output is rated at 7.8 HP (5.7 kW) at 6,000 rpm while maximum torque reaches 9.2 Nm (6.7 lb-ft) at 5,000 rpm, transferring power to the rear wheel through a 4-speed gearbox and belt final drive. With a specific output of 62.4 HP per liter and a 1,000 rpm working window between peak torque (5,000 rpm) and peak power (6,000 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 Star 4S 125 Classic measures 121 kg (267 lbs) dry, translating to a power-to-weight ratio of 0.06 HP/kg (15.51 kg per horsepower). Rider ergonomics and chassis geometry center around a 1,235 mm (48.6 in) wheelbase engineered for quick, flickable steering geometry. The 5.5-liter (1.5 US gal) fuel tank supports practical everyday commuting and weekend road stints.
