The name came from the participation at the 26th International Six Days in 1951, where 9 gold medals were won. The Piaggio Racing Team was composed of: Biasci, Cau, Crabs, Mazzoncini, Merlo, Nesti, Opesso, Riva, Romano and Vivaldi. The Vespa 125 "Six Days" also won the trophy of the Italian Motorcycle Federation in 1951, which saw 3 riders dominate on Italian Vespas (Giuseppe Cau, Miro Riva, Bruno Romano).

In 1951 Vespa broke its most prestigious record: the flying kilometer. On February 9th, between the 10th and the 11th kilometer of the motorway of Rome (near to Ostia), a Vespa engine with two opposed pistons (17.2 hp and 9500 rpm), designed by Corradino D’Ascanio, and led by Dino Mazzoncini, run the flying kilometer with a record time of 21.4 seconds with an average speed of 171.1 km/h (106.25 mph).
