2016 AJS R7 Technical Analysis & Specification Breakdown

Built around AJS's sport motorcycle platform, the 2016 AJS R7 relies on a 124 cc (7.6 cu in) liquid-cooled single cylinder, four-stroke powerplant. In factory specification, peak output is rated at 15 HP (10.9 kW) at 8,500 rpm, transferring power to the rear wheel through a 5-speed gearbox and chain final drive. With a specific output of 121 HP per liter, the engine character is reflecting a performance-oriented street tune that balances strong mid-range pull with an energetic top-end rush.

On the scales, the R7 measures 127 kg (280 lbs) dry, translating to a power-to-weight ratio of 0.12 HP/kg (8.47 kg per horsepower). Rider ergonomics and chassis geometry center around a 810 mm (31.9 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,333 mm (52.5 in) wheelbase engineered for quick, flickable steering geometry. The 18.5-liter (4.9 US gal) fuel tank supports practical everyday commuting and weekend road stints, while factory top speed is listed at 90 km/h (56 mph).
