At the heart of the 2012 LML Star 4S 125 Prestige scooter motorcycle, LML pairs a 124.9 cc (7.6 cu in) air-cooled single cylinder, four-stroke architecture with road-focused gearing. 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 Prestige measures 122 kg (269 lbs) dry, translating to a power-to-weight ratio of 0.06 HP/kg (15.64 kg per horsepower). Rider ergonomics and chassis geometry center around a 820 mm (32.3 in) seat height — resulting in a taller command-style riding posture suited to medium-to-tall inseams, combined with a 1,235 mm (48.6 in) wheelbase engineered for quick, flickable steering geometry. The 5.5-liter (1.5 US gal) fuel tank paired with a rated consumption of 1.67 L/100 km provides an estimated theoretical range of roughly 329 km (204 miles) between fill-ups, while factory top speed is listed at 83 km/h (52 mph).
