Technical Overview
2016 AJS Eos 125 Technical Analysis & Specification Breakdown
At the heart of the 2016 AJS Eos 125 custom - cruiser motorcycle, AJS utilizes a 124.6 cc (7.6 cu in) liquid-cooled twin, four-stroke layout. In factory specification, peak output is rated at 10.7 HP (7.8 kW) at 9,500 rpm, transferring power to the rear wheel through a 5-speed gearbox and chain final drive. With a specific output of 85.9 HP per liter, the engine character is indicating a tractable, stress-free state of tune focused on everyday usability and broad torque delivery.
On the scales, the Eos 125 measures 180 kg (397 lbs) dry, translating to a power-to-weight ratio of 0.06 HP/kg (16.82 kg per horsepower). Rider ergonomics and chassis geometry center around a 640 mm (25.2 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 1,850 mm (72.8 in) wheelbase engineered for planted straight-line stability. The 13.5-liter (3.6 US gal) fuel tank supports practical everyday commuting and weekend road stints, while factory top speed is listed at 97 km/h (60 mph).
