The Lambretta TV 175 and TV 200 series three were seen as the natural evolution of the Slimstyle series which had been introduced in late 1961. The TV 175 was regarded as the pinnacle of Lambretta engineering and design by Innocenti, that was challenged by Lambretta Concessionaires and in particular, Peter Agg who felt it could be taken further. This eventually led to the creation of the TV 200 and in doing so changed Lambretta production forever.
