Positioned in Piaggio's scooter motorcycle lineup, the 2011 Piaggio Fly 125 utilizes a 125 cc (7.6 cu in) air-cooled single cylinder, four-stroke layout. In factory specification, peak output is rated at 14.8 HP (10.8 kW) at 9,750 rpm while maximum torque reaches 12 Nm (8.9 lb-ft) at 8,000 rpm, transferring power to the rear wheel through a automatic gearbox. With a specific output of 118.4 HP per liter and a 1,750 rpm working window between peak torque (8,000 rpm) and peak power (9,750 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 Fly 125 measures 121 kg (267 lbs) wet (curb), translating to a power-to-weight ratio of 0.12 HP/kg (8.18 kg per horsepower). The 7.5-liter (2 US gal) fuel tank supports practical everyday commuting and weekend road stints.
