Built around Keeway's scooter motorcycle platform, the 2006 Keeway ARN 125 features a 124.6 cc (7.6 cu in) air-cooled single cylinder, two-stroke configuration. In factory specification, peak output is rated at 6.8 HP (5 kW) at 6,750 rpm while maximum torque reaches 7.6 Nm (5.6 lb-ft) at 5,500 rpm. With a specific output of 54.6 HP per liter and a 1,250 rpm working window between peak torque (5,500 rpm) and peak power (6,750 rpm), the engine character is prioritizing low-RPM tractability, mechanical longevity and relaxed throttle response over peak redline numbers.
On the scales, the ARN 125 measures 105 kg (231 lbs) dry, translating to a power-to-weight ratio of 0.06 HP/kg (15.44 kg per horsepower). Rider ergonomics and chassis geometry center around a 1,265 mm (49.8 in) wheelbase engineered for quick, flickable steering geometry. The 5.2-liter (1.4 US gal) fuel tank supports practical everyday commuting and weekend road stints, while factory top speed is listed at 82 km/h (51 mph).

Weight
Compare weight carefully because it affects low-speed handling, parking and confidence.
Fuel Capacity
Fuel capacity helps estimate touring range and how often you may need to stop.
Brakes
Brake setup is worth comparing if you ride in traffic, mountains or with a passenger.
