Positioned in Keeway's scooter motorcycle lineup, the 2008 Keeway Hacker 125 utilizes a 124.6 cc (7.6 cu in) air-cooled single cylinder, four-stroke layout. In factory specification, peak output is rated at 9.8 HP (7.1 kW) at 8,000 rpm while maximum torque reaches 9.7 Nm (7.2 lb-ft) at 6,500 rpm, transferring power to the rear wheel through a automatic gearbox and belt final drive. With a specific output of 78.7 HP per liter and a 1,500 rpm working window between peak torque (6,500 rpm) and peak power (8,000 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 Hacker 125 measures 115 kg (254 lbs) dry, translating to a power-to-weight ratio of 0.09 HP/kg (11.73 kg per horsepower). Rider ergonomics and chassis geometry center around a 1,500 mm (59.1 in) wheelbase engineered for balanced agility and highway composure. The 3.5-liter (0.9 US gal) fuel tank paired with a rated consumption of 2.4 L/100 km provides an estimated theoretical range of roughly 146 km (91 miles) between fill-ups, while factory top speed is listed at 83 km/h (52 mph).
