Positioned in Keeway's scooter motorcycle lineup, the 2007 Keeway ARN 150cc utilizes a 150 cc (9.2 cu in) single cylinder, four-stroke layout. In factory specification, peak output is rated at 9.4 HP (6.8 kW) at 7,500 rpm while maximum torque reaches 9 Nm (6.6 lb-ft) at 6,000 rpm, transferring power to the rear wheel through a automatic gearbox. With a specific output of 62.7 HP per liter and a 1,500 rpm working window between peak torque (6,000 rpm) and peak power (7,500 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 ARN 150cc measures 150 kg (331 lbs) dry, translating to a power-to-weight ratio of 0.06 HP/kg (15.96 kg per horsepower). Rider ergonomics and chassis geometry center around a 1,300 mm (51.2 in) wheelbase engineered for quick, flickable steering geometry. The 5.2-liter (1.4 US gal) fuel tank paired with a rated consumption of 2.8 L/100 km provides an estimated theoretical range of roughly 186 km (116 miles) between fill-ups, while factory top speed is listed at 88 km/h (55 mph).
