At the heart of the 1998 Aprilia Leonardo 125 scooter motorcycle, Aprilia features a 125 cc (7.6 cu in) air-cooled single cylinder, four-stroke configuration. In factory specification, peak output is rated at 12 HP (8.8 kW) at 8,800 rpm while maximum torque reaches 12 Nm (8.9 lb-ft). With a specific output of 96 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 Leonardo 125 measures 130 kg (287 lbs) dry, translating to a power-to-weight ratio of 0.09 HP/kg (10.83 kg per horsepower). Rider ergonomics and chassis geometry center around a 860 mm (33.9 in) seat height — reflecting a long-travel chassis stance that favors ground clearance and off-pavement control.
