At the heart of the 2007 Vespa Granturismo GT 125L scooter motorcycle, Vespa utilizes a 124 cc (7.6 cu in) liquid-cooled single cylinder, four-stroke layout. In factory specification, peak output is rated at 14.8 HP (10.8 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 automatic gearbox and belt final drive. With a specific output of 119.4 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 Granturismo GT 125L measures 138 kg (304 lbs) wet (curb), translating to a power-to-weight ratio of 0.11 HP/kg (9.32 kg per horsepower). Rider ergonomics and chassis geometry center around a 790 mm (31.1 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,395 mm (54.9 in) wheelbase engineered for quick, flickable steering geometry. The 10-liter (2.6 US gal) fuel tank supports practical everyday commuting and weekend road stints, while factory top speed is listed at 102 km/h (63 mph).
