Built around Vespa's scooter motorcycle platform, the 2011 Vespa GTV 300 utilizes a 278 cc (17 cu in) air-cooled single cylinder, four-stroke layout. In factory specification, peak output is rated at 21.2 HP (15.5 kW) at 7,500 rpm while maximum torque reaches 20.2 Nm (14.9 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 76.3 HP per liter and a 1,000 rpm working window between peak torque (6,500 rpm) and peak power (7,500 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 GTV 300 measures 148 kg (326 lbs) dry, translating to a power-to-weight ratio of 0.14 HP/kg (6.98 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 1,394 mm (54.9 in) wheelbase engineered for quick, flickable steering geometry. The 9-liter (2.4 US gal) fuel tank paired with a rated consumption of 3.48 L/100 km provides an estimated theoretical range of roughly 259 km (161 miles) between fill-ups.
