At the heart of the 1966 Vespa 180 Supersport scooter motorcycle, Vespa utilizes a 181.1 cc (11.1 cu in) air-cooled single cylinder, two-stroke layout. In factory specification, peak output is rated at 10 HP (7.3 kW) at 6,250 rpm, transferring power to the rear wheel through a 4-speed gearbox and chain final drive. With a specific output of 55.2 HP per liter, the engine character is prioritizing low-RPM tractability, mechanical longevity and relaxed throttle response over peak redline numbers.
On the scales, the 180 Supersport measures 116 kg (256 lbs) dry, translating to a power-to-weight ratio of 0.09 HP/kg (11.6 kg per horsepower). Rider ergonomics and chassis geometry center around a 1,230 mm (48.4 in) wheelbase engineered for quick, flickable steering geometry.
