In 1944 Piaggio engineers Renzo Spolti and Vittorio Casini designed a motorcycle with bodywork fully enclosing the drivetrain and forming a tall splash guard at the front. In addition to the bodywork, the design included handlebar-mounted controls, forced air cooling, wheels of small diameter, and a tall central section that had to be straddled.  Officially known as the MP5 ("Moto Piaggio no. 5"), the prototype was nicknamed "Paperino" (meaning "Donald Duck" in Italian).<ref name="Vespa46_06pp80_83" />
Piaggio was displeased with the MP5, especially the tall central section.  He contracted [[Aerospace engineering|aeronautical engineer]] [[Corradino D'Ascanio]], to redesign the scooter.<ref name="Vespa46_06pp80_83"/>  D'Ascanio, who had earlier been consulted by [[Ferdinando Innocenti]] about scooter design and manufacture, made it immediately known that he hated motorcycles, believing them to be bulky, dirty, and unreliable.<ref name="RedEyes2022"/>

D'Ascanio's MP6 prototype had its engine mounted beside the rear wheel.  The wheel was driven directly from the transmission, eliminating the drive chain and the oil and dirt associated with it. The prototype had a unit spar frame with stress-bearing steel outer panels.<ref name="RedEyes2022"/>  These changes allowed the MP6 to have a step-through design instead of a tall centre section like that of the MP5 Paperino. The MP6 design also included a single-sided front suspension, interchangeable front and rear wheels mounted on stub axles, and a spare wheel. Other features of the MP6 were similar to those on the Paperino, including the handlebar-mounted controls and the enclosed bodywork with the tall front splash guard.<ref name="Vespa46_06pp80_83"/>

Upon seeing the MP6 for the first time, Enrico Piaggio exclaimed: "Sembra una vespa!" ("It looks like a wasp!") Piaggio effectively named his new scooter on the spot.<ref name="RedEyes2022" /><ref name="thecarconnection.com"/> ''Vespa'' is both [[Latin]] and Italian for wasp—derived from the vehicle's body shape: the thicker rear part connected to the front part by a narrow waist, and the steering rod resembled [[antenna (biology)|antennae]].{{fact|date=May 2025}}
