2021 Vespa GTS Super 125 Racing Sixties Technical Analysis & Specification Breakdown
At the heart of the 2021 Vespa GTS Super 125 Racing Sixties scooter motorcycle, Vespa features a 124.7 cc (7.6 cu in) liquid-cooled single cylinder, four-stroke configuration. In factory specification, peak output is rated at 13.8 HP (10.1 kW) at 8,750 rpm while maximum torque reaches 11.1 Nm (8.2 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 110.7 HP per liter and a 2,000 rpm working window between peak torque (6,750 rpm) and peak power (8,750 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 Super 125 Racing Sixties measures 160 kg (353 lbs) dry, translating to a power-to-weight ratio of 0.09 HP/kg (11.59 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. The 7-liter (1.8 US gal) fuel tank paired with a rated consumption of 2 L/100 km provides an estimated theoretical range of roughly 350 km (217 miles) between fill-ups, while factory top speed is listed at 101 km/h (63 mph).
