Positioned in Vespa's scooter motorcycle lineup, the 2007 Vespa PX 125 utilizes a 123.4 cc (7.5 cu in) air-cooled single cylinder, two-stroke layout. In factory specification, peak output is rated at 12 HP (8.8 kW) at 6,600 rpm while maximum torque reaches 9.6 Nm (7.1 lb-ft) at 6,000 rpm, transferring power to the rear wheel through a 4-speed gearbox. With a specific output of 97.2 HP per liter and a 600 rpm working window between peak torque (6,000 rpm) and peak power (6,600 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 PX 125 measures 97 kg (214 lbs) dry, translating to a power-to-weight ratio of 0.12 HP/kg (8.08 kg per horsepower). Rider ergonomics and chassis geometry center around a 1,260 mm (49.6 in) wheelbase engineered for quick, flickable steering geometry. The 8-liter (2.1 US gal) fuel tank supports practical everyday commuting and weekend road stints, while factory top speed is listed at 87 km/h (54 mph).
