At the heart of the 2009 Vespa GTS 250ie scooter motorcycle, Vespa relies on a 244 cc (14.9 cu in) liquid-cooled single cylinder, four-stroke powerplant. In factory specification, peak output is rated at 21.3 HP (15.5 kW) at 8,250 rpm while maximum torque reaches 20.1 Nm (14.8 lb-ft) at 6,500 rpm, transferring power to the rear wheel through a automatic gearbox. With a specific output of 87.3 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 indicating a tractable, stress-free state of tune focused on everyday usability and broad torque delivery.
On the scales, the GTS 250ie measures 151 kg (333 lbs) dry, translating to a power-to-weight ratio of 0.14 HP/kg (7.09 kg per horsepower). Rider ergonomics and chassis geometry center around a 1,370 mm (53.9 in) wheelbase engineered for quick, flickable steering geometry. The 9.2-liter (2.4 US gal) fuel tank supports practical everyday commuting and weekend road stints.
