Technical Overview
1991 Vespa Cosa 200 GS Technical Analysis & Specification Breakdown
Built around Vespa's scooter motorcycle platform, the 1991 Vespa Cosa 200 GS utilizes a 198 cc (12.1 cu in) air-cooled single cylinder, two-stroke layout. In factory specification, peak output is rated at 12 HP (8.8 kW) at 6,000 rpm, transferring power to the rear wheel through a 4-speed gearbox. With a specific output of 60.6 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 Cosa 200 GS measures 130 kg (287 lbs) wet (curb), translating to a power-to-weight ratio of 0.09 HP/kg (10.83 kg per horsepower). Rider ergonomics and chassis geometry center around a 815 mm (32.1 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,270 mm (50 in) wheelbase engineered for quick, flickable steering geometry. The 7-liter (1.8 US gal) fuel tank paired with a rated consumption of 4 L/100 km provides an estimated theoretical range of roughly 175 km (109 miles) between fill-ups, while factory top speed is listed at 100 km/h (62 mph).
