2019 Vespa GTS Super 300 Technical Analysis & Specification Breakdown
Positioned in Vespa's scooter motorcycle lineup, the 2019 Vespa GTS Super 300 relies on a 278 cc (17 cu in) liquid-cooled single cylinder, four-stroke powerplant. In factory specification, peak output is rated at 21.2 HP (15.5 kW) at 7,750 rpm while 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. With a specific output of 76.3 HP per liter and a 2,750 rpm working window between peak torque (5,000 rpm) and peak power (7,750 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 Super 300 measures 158 kg (348 lbs) dry, translating to a power-to-weight ratio of 0.13 HP/kg (7.45 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 1,950 mm (76.8 in) wheelbase engineered for planted straight-line stability. The 8.5-liter (2.2 US gal) fuel tank paired with a rated consumption of 3.3 L/100 km provides an estimated theoretical range of roughly 258 km (160 miles) between fill-ups, while factory top speed is listed at 129 km/h (80 mph).
