in Italin language:

"Chi non vespa si fa le pere" by Vasco Rossi

che per paragone intende che chi si fa le pere è colui che si buca usando eroina, pertanto chi usa la Vespa è colui che si porta la fidanzata in campagna per scopare.
Quindi chi non Vespa è chi non scopa e quindi si droga.

"Whoever Doesn't Wasp Makes Pears" by Vasco Rossi

which by comparison means that the person who makes pears is the one who punctures himself using heroin, therefore the person who uses the Vespa is the one who takes his girlfriend to the countryside to fuck.
So he who doesn't Vespa is he who doesn't fuck and therefore takes drugs.

p.s. Vespa is a motobike by Piaggio
