Engineered by Piaggio for the scooter motorcycle segment, the 2011 Piaggio Fly 150 relies on a 150 cc (9.2 cu in) air-cooled single cylinder, four-stroke powerplant. In factory specification, peak output is rated at 11.4 HP (8.3 kW) at 7,750 rpm while maximum torque reaches 11.5 Nm (8.5 lb-ft) at 8,000 rpm, transferring power to the rear wheel through a automatic gearbox and belt final drive. With a specific output of 76 HP per liter, 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 150 measures 112 kg (247 lbs) wet (curb), translating to a power-to-weight ratio of 0.1 HP/kg (9.82 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 7.1-liter (1.9 US gal) fuel tank supports practical everyday commuting and weekend road stints.
