At the heart of the 2015 ajp pr4 125 supermoto super motard motorcycle, ajp relies on a 124 cc (7.6 cu in) air-cooled single cylinder, four-stroke powerplant. In factory specification, peak output is rated at 12.6 HP (9.2 kW) at 8,400 rpm while maximum torque reaches 8.5 Nm (6.3 lb-ft), transferring power to the rear wheel through a 5-speed gearbox and chain final drive. With a specific output of 101.6 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 112 kg (247 lbs) wet (curb), translating to a power-to-weight ratio of 0.11 HP/kg (8.89 kg per horsepower). Rider ergonomics and chassis geometry center around a 840 mm (33.1 in) seat height — resulting in a taller command-style riding posture suited to medium-to-tall inseams, combined with a 1,389 mm (54.7 in) wheelbase engineered for quick, flickable steering geometry. The 7.5-liter (2 US gal) fuel tank supports practical everyday commuting and weekend road stints.
