The “Sei Giorni” model was one of the most significant of all Vespas. Highly sought after by collectors, only 300 models were produced, destined for regularity rallies. It took its name from the International Six Days Enduro race, for which it was specifically designed. Compared to the normal 125 cc model, it featured a more powerful engine with a Dell’Orto SS 23P carburettor. The clutch was strengthened, like the bodywork, which was also much more aerodynamic.
