2015 ajp pr7 Technical Analysis & Specification Breakdown

Engineered by ajp for the prototype - concept model motorcycle segment, the 2015 ajp pr7 pairs a 659.7 cc (40.3 cu in) liquid-cooled single cylinder, four-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 48 HP (35 kW) at 6,000 rpm while maximum torque reaches 58 Nm (42.8 lb-ft) at 5,500 rpm, transferring power to the rear wheel through a 5-speed gearbox and chain final drive. With a specific output of 72.8 HP per liter and a 500 rpm working window between peak torque (5,500 rpm) and peak power (6,000 rpm), the engine character is indicating a tractable, stress-free state of tune focused on everyday usability and broad torque delivery.

On the scales, the pr7 measures 155 kg (342 lbs) dry, translating to a power-to-weight ratio of 0.31 HP/kg (3.23 kg per horsepower). Rider ergonomics and chassis geometry center around a 920 mm (36.2 in) seat height — reflecting a long-travel chassis stance that favors ground clearance and off-pavement control, combined with a 1,532 mm (60.3 in) wheelbase engineered for planted straight-line stability. The 17-liter (4.5 US gal) fuel tank supports practical everyday commuting and weekend road stints.
