Engineered by AJS for the scooter motorcycle segment, the 2010 AJS Exactly 125 features a 124 cc (7.6 cu in) air-cooled single cylinder, four-stroke configuration. In factory specification, peak output is rated at 6.2 HP (4.5 kW) at 7,500 rpm, transferring power to the rear wheel through a automatic gearbox and belt final drive. With a specific output of 50 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 Exactly 125 measures 89 kg (196 lbs) dry, translating to a power-to-weight ratio of 0.07 HP/kg (14.35 kg per horsepower). Rider ergonomics and chassis geometry center around a 775 mm (30.5 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,290 mm (50.8 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.
Within MotoLibrary's AJS archive, this model family spans 2 indexed model years from 2010 to 2011, allowing buyers to track year-over-year changes in emissions tuning, weight and equipment.
