Euro style rear variator and clutch for Vespa Ciao, Bravo, Si, etc. Might have to make a few adjustments to fit on some Ciao. Some newer ones have a slightly different frame near the transmission to accommodate this variator
You must have the variated rear transmission to use this. 3 step bell! Some say these are the strongest of the stock bells. You can also use clutch springs to really liven up your bike.
