Engineered by AJS for the scooter motorcycle segment, the 2015 AJS A9 Flight 125 relies on a 124 cc (7.6 cu in) air-cooled single cylinder, four-stroke powerplant. In factory specification, peak output is rated at 7.4 HP (5.4 kW) at 7,500 rpm, transferring power to the rear wheel through a automatic gearbox and belt final drive. With a specific output of 59.7 HP per liter, the engine character is prioritizing low-RPM tractability, mechanical longevity and relaxed throttle response over peak redline numbers.
On the scales, the A9 Flight 125 measures 107 kg (236 lbs) dry, translating to a power-to-weight ratio of 0.07 HP/kg (14.46 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 1,382 mm (54.4 in) wheelbase engineered for quick, flickable steering geometry. The 4.7-liter (1.2 US gal) fuel tank supports practical everyday commuting and weekend road stints, while factory top speed is listed at 81 km/h (50 mph).
