Built around Ajp's super motard motorcycle platform, the 2020 Ajp PR3 Supermoto 125 features a 125 cc (7.6 cu in) air-cooled single cylinder, four-stroke configuration. In factory specification, peak output is rated at 12.6 HP (9.2 kW) at 8,500 rpm while maximum torque reaches 8.5 Nm (6.3 lb-ft) at 8,000 rpm, transferring power to the rear wheel through a 5-speed gearbox and chain final drive. With a specific output of 100.8 HP per liter and a 500 rpm working window between peak torque (8,000 rpm) and peak power (8,500 rpm), 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 PR3 Supermoto 125 measures 104 kg (229 lbs) dry, translating to a power-to-weight ratio of 0.12 HP/kg (8.25 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 1,360 mm (53.5 in) wheelbase engineered for quick, flickable steering geometry. The 7-liter (1.8 US gal) fuel tank supports practical everyday commuting and weekend road stints.
