Positioned in AJS's custom - cruiser motorcycle lineup, the 2014 AJS SPT 350 pairs a 320 cc (19.5 cu in) liquid-cooled twin, four-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 23 HP (16.8 kW) at 8,000 rpm, transferring power to the rear wheel through a 5-speed gearbox and chain final drive. With a specific output of 71.9 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 SPT 350 measures 156 kg (344 lbs) dry, translating to a power-to-weight ratio of 0.15 HP/kg (6.78 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 1,470 mm (57.9 in) wheelbase engineered for balanced agility and highway composure. The 28-liter (7.4 US gal) fuel tank supports practical everyday commuting and weekend road stints.
