Built around AJS's scooter motorcycle platform, the 2015 AJS Sorvio 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 7.1 HP (5.2 kW) at 7,500 rpm, transferring power to the rear wheel through a automatic gearbox and belt final drive. With a specific output of 57 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 Sorvio 125 measures 98 kg (216 lbs) dry, translating to a power-to-weight ratio of 0.07 HP/kg (13.8 kg per horsepower). Rider ergonomics and chassis geometry center around a 735 mm (28.9 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 1,305 mm (51.4 in) wheelbase engineered for quick, flickable steering geometry. The 6-liter (1.6 US gal) fuel tank supports practical everyday commuting and weekend road stints, while factory top speed is listed at 85 km/h (53 mph).
