Engineered by ajp for the super motard motorcycle segment, the 2003 ajp pr4 supermoto features a 124 cc (7.6 cu in) single cylinder, four-stroke configuration. In factory specification, peak output is rated at 12.6 HP (9.2 kW) at 8,500 rpm. 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.

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.
