这款赛车在1951年举办的第26届国际六日大赛中赢得9项金牌,因而名声大噪。Piaggio车队的成员有:Biasci、Cau、Granchi、Mazzoncini、Merlo、Nesti、Opessi、Riva、Romano及Vivaldi。1951年,Vespa 125 Sei Giorni也在意大利摩托车联盟盃中获奖。
The legendary Vespa 150 Gran Sport established itself in 1955 with the model VS1. This model was adapted and the VS5 version was equipped with a special speedometer fan and a fully chromed tail light with integrated brake light. It also had an improved braking system and the Piaggio creston the front fender. The Vespa 150 GS (VS5) model holds the record for the number of units built (80,000) and was produced between 1958 and 1961.
Vespa Super Sport 180畅销的成功基础上,Piaggio随即于1968年推出新款的180 cc车款,它的机械系统与车架系以1966年Vespa Sprint彻底改良而成,而龙头把手、置物箱及坐垫也变得更为美观。至今,Vespa Rally 180仍是功能最齐全、外型又最迷人的车款之一。在1968至1973年之间,共有26,000辆180 Rally出厂。
