At the heart of the 2019 Keeway Superlight 125 Limited E4 custom - cruiser motorcycle, Keeway relies on a 124 cc (7.6 cu in) air-cooled single cylinder, four-stroke powerplant. In factory specification, peak output is rated at 10.5 HP (7.6 kW) at 9,000 rpm while maximum torque reaches 8.9 Nm (6.6 lb-ft) at 7,500 rpm, transferring power to the rear wheel through a 5-speed gearbox and chain final drive. With a specific output of 84.7 HP per liter and a 1,500 rpm working window between peak torque (7,500 rpm) and peak power (9,000 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 Superlight 125 Limited E4 measures 134 kg (295 lbs) dry, translating to a power-to-weight ratio of 0.08 HP/kg (12.76 kg per horsepower). Rider ergonomics and chassis geometry center around a 730 mm (28.7 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 1,440 mm (56.7 in) wheelbase engineered for balanced agility and highway composure. The 15-liter (4 US gal) fuel tank supports practical everyday commuting and weekend road stints.
