Built around ajp's super motard motorcycle platform, the 2006 ajp pr4 125 supermotard utilizes a 124 cc (7.6 cu in) air-cooled single cylinder, four-stroke layout. In factory specification, peak output is rated at 12.7 HP (9.3 kW) at 8,500 rpm, transferring power to the rear wheel through a 5-speed gearbox. With a specific output of 102.4 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 101 kg (223 lbs) dry, translating to a power-to-weight ratio of 0.13 HP/kg (7.95 kg per horsepower). Rider ergonomics and chassis geometry center around a 905 mm (35.6 in) seat height — reflecting a long-travel chassis stance that favors ground clearance and off-pavement control, combined with a 1,410 mm (55.5 in) wheelbase engineered for quick, flickable steering geometry. The 8-liter (2.1 US gal) fuel tank supports practical everyday commuting and weekend road stints.
