The heart of the legend is the engine. The standard Vespa PX 200 (the largest displacement available from Piaggio at the time) had a 198cc engine. The "200" referred to the approximate cubic centimeters.

In the late 1980s, the Miguel Indurain of scooter racing was a dangerous game. There were no wind tunnels, no traction control—just instinct, courage, and raw fuel.
Marco Papa famously piloted his 304cc Vespa at the Ostia racetrack (a street circuit near Rome) and on the Autodromo Nazionale di Monza . Video footage (now grainy, but terrifying) shows Papa laying flat on the saddle, feet on the rear footpegs, chin over the headset, while the rev counter screamed past 9,000 RPM.
