Positioned in ajp's super motard motorcycle lineup, the 2005 ajp pr4 125 supermotard utilizes a 125 cc (7.6 cu in) air-cooled single cylinder, four-stroke layout. In factory specification, peak output is rated at 14.8 HP (10.8 kW), transferring power to the rear wheel through a 5-speed gearbox and chain final drive. With a specific output of 118.4 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 pr4 125 supermotard measures 99 kg (218 lbs) dry, translating to a power-to-weight ratio of 0.15 HP/kg (6.69 kg per horsepower). Rider ergonomics and chassis geometry center around a 850 mm (33.5 in) seat height — resulting in a taller command-style riding posture suited to medium-to-tall inseams, combined with a 1,410 mm (55.5 in) wheelbase engineered for quick, flickable steering geometry. The 9-liter (2.4 US gal) fuel tank supports practical everyday commuting and weekend road stints.
