Engineered by ajp for the super motard motorcycle segment, the 2008 ajp pr4 125 supermoto relies on a 124 cc (7.6 cu in) air-cooled single cylinder, four-stroke powerplant. In factory specification, peak output is rated at 12.5 HP (9.1 kW) at 8,500 rpm, transferring power to the rear wheel through a 5-speed gearbox. With a specific output of 100.8 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 supermoto measures 101 kg (223 lbs) dry, translating to a power-to-weight ratio of 0.12 HP/kg (8.08 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.
