Built around Vespa's scooter motorcycle platform, the 2019 Vespa GTS utilizes a 125 cc (7.6 cu in) liquid-cooled single cylinder, four-stroke layout. In factory specification, peak output is rated at 12.1 HP (8.8 kW) at 8,250 rpm while maximum torque reaches 11 Nm (8.1 lb-ft) at 6,750 rpm, transferring power to the rear wheel through a automatic gearbox and belt final drive. With a specific output of 96.8 HP per liter and a 1,500 rpm working window between peak torque (6,750 rpm) and peak power (8,250 rpm), the engine character is reflecting a performance-oriented street tune that balances strong mid-range pull with an energetic top-end rush.
On the scales, the GTS measures 158 kg (348 lbs) dry, translating to a power-to-weight ratio of 0.08 HP/kg (13.06 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 7-liter (1.8 US gal) fuel tank supports practical everyday commuting and weekend road stints.
