At the heart of the 2018 Piaggio Medley 125 scooter motorcycle, Piaggio features a 124.9 cc (7.6 cu in) liquid-cooled single cylinder, four-stroke configuration. In factory specification, peak output is rated at 12.1 HP (8.8 kW) at 8,250 rpm while maximum torque reaches 11.5 Nm (8.5 lb-ft) at 6,500 rpm, transferring power to the rear wheel through a automatic gearbox and belt final drive. With a specific output of 96.9 HP per liter and a 1,750 rpm working window between peak torque (6,500 rpm) and peak power (8,250 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 Medley 125 measures 132 kg (291 lbs) wet (curb), translating to a power-to-weight ratio of 0.09 HP/kg (10.91 kg per horsepower). Rider ergonomics and chassis geometry center around a 799 mm (31.5 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,390 mm (54.7 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.
