In 1948, Piaggio launched a new Vespa. Between 1946 and 1947, 1183 125cc Vespas were sold and marketed abroad (mainly in Switzerland). At the end of 1947, Enrico Piaggio decided to completely stop production of the Vespa 98cc and continue with only 125cc for the Italian and international markets.

Some other adaptations of the model were the front suspension arm, the raised engine hood that allowed easier access to the engine and other mechanical components.

The next series of the 1949 Vespa, which is now on display at the Piaggio Museum, was even better with the new cooling system and revamped gearbox controls.
