Technical Overview
2005 Vespa Granturismo 125 L Technical Analysis & Specification Breakdown
Engineered by Vespa for the scooter motorcycle segment, the 2005 Vespa Granturismo 125 L pairs a 124 cc (7.6 cu in) liquid-cooled single cylinder, four-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 14.8 HP (10.8 kW) at 10,000 rpm, transferring power to the rear wheel through a automatic gearbox. With a specific output of 119.4 HP per liter, 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 Granturismo 125 L measures 138 kg (304 lbs) dry, translating to a power-to-weight ratio of 0.11 HP/kg (9.32 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 1,395 mm (54.9 in) wheelbase engineered for quick, flickable steering geometry. The 10-liter (2.6 US gal) fuel tank paired with a rated consumption of 4 L/100 km provides an estimated theoretical range of roughly 250 km (155 miles) between fill-ups, while factory top speed is listed at 102 km/h (63 mph).
