2021 Ajp PR7 Technical Analysis & Specification Breakdown

Positioned in Ajp's sport motorcycle lineup, the 2021 Ajp PR7 features a 600 cc (36.6 cu in) liquid-cooled single cylinder, four-stroke configuration. 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), transferring power to the rear wheel through a 5-speed gearbox and chain final drive. With a specific output of 80 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 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 1,540 mm (60.6 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.

Within MotoLibrary's Ajp archive, this model family spans 2 indexed model years from 2015 to 2021, allowing buyers to track year-over-year changes in emissions tuning, weight and equipment.
