Built around Vespa's scooter motorcycle platform, the 2019 Vespa GTS SuperTech relies on a 278 cc (17 cu in) liquid-cooled single cylinder, four-stroke powerplant. In factory specification, peak output is rated at 23.8 HP (17.4 kW) at 8,250 rpm, transferring power to the rear wheel through a automatic gearbox and belt final drive. With a specific output of 85.6 HP per liter, 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 SuperTech measures 160 kg (353 lbs) dry, translating to a power-to-weight ratio of 0.15 HP/kg (6.72 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 1,375 mm (54.1 in) wheelbase engineered for quick, flickable steering geometry. The 8.5-liter (2.2 US gal) fuel tank paired with a rated consumption of 3.36 L/100 km provides an estimated theoretical range of roughly 253 km (157 miles) between fill-ups, while factory top speed is listed at 129 km/h (80 mph).
