Built around Piaggio's scooter motorcycle platform, the 2007 Piaggio Fly 125 pairs a 124 cc (7.6 cu in) air-cooled single cylinder, four-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 10.5 HP (7.7 kW) at 8,000 rpm while maximum torque reaches 10 Nm (7.4 lb-ft) at 7,000 rpm, transferring power to the rear wheel through a automatic gearbox and belt final drive. With a specific output of 84.7 HP per liter and a 1,000 rpm working window between peak torque (7,000 rpm) and peak power (8,000 rpm), the engine character is indicating a tractable, stress-free state of tune focused on everyday usability and broad torque delivery.
On the scales, the Fly 125 measures 106 kg (234 lbs) wet (curb), translating to a power-to-weight ratio of 0.1 HP/kg (10.1 kg per horsepower). Rider ergonomics and chassis geometry center around a 785 mm (30.9 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance. The 7.2-liter (1.9 US gal) fuel tank supports practical everyday commuting and weekend road stints.
