Positioned in Vespa's scooter motorcycle lineup, the 2011 Vespa GTS 300 relies on a 278 cc (17 cu in) liquid-cooled single cylinder, four-stroke powerplant. In factory specification, maximum torque reaches 22.3 Nm (16.4 lb-ft) at 5,000 rpm, transferring power to the rear wheel through a automatic gearbox and belt final drive. Internal engine geometry specifies a bore and stroke of 75.0 x 63.0 mm (3.0 x 2.5 inches).
On the scales, the GTS 300 measures 158 kg (348 lbs) dry. 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. The 9.2-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 264 km (164 miles) between fill-ups, while factory top speed is listed at 129 km/h (80 mph).
Within MotoLibrary's Vespa archive, this model family spans 9 indexed model years from 2011 to 2024, allowing buyers to track year-over-year changes in emissions tuning, weight and equipment.
