I think he’s asking how to mount a Fox clutch on a vespa ciao, not what it is (in fact, it is a vario clutch, a part of the variomatic system).

Well, if you want to mount a clutch like this on your vespa you need to buy a Fox axle: the axle this clutch originally is mounted on. Then you got to attach the part you mount the clutch on, to the gear part of an original Vespa vario axle.

jmpb for example.

but you can look around on this site for an occasion.
that is not that expensive.

an new variomatic system +.- 400,- euro.
than u got an mollossi system

but you need another rear gearingcase. a good one costs between 85,- and 150,- euro
more as 150,- you don’t got to pay for it, more is not fair.
and newones don’t exists, they’r not in production anymore.

this is an link to a part of v-c.nl how you got to mount a variomatic system,
its dutch but maibe u can translate it.

also you can see on the pictures the parts u need.

this is a site where you can buy all the stuff, exept the gear case.

this is what you need

achterkoppeling cpl imi vespa 49,-
malossi variateur vespa 59,-
V snaar vespa 15,- (order the good vsnaar for your model moped)

and the pressure spring in the rear clutch, is not so good.
u can better instal the yellow one what’s included by the variomatic kit.

I hope u can moveon whit this information.
you can PM me always for more quistions

You will have to combine 2 shafts:

Edjuh e simpatissimimo come se fosse un italiano DOC….:D
La curiosita e donna, dicono gli italiani credo eheh!

Ma secondo me questo e un forum olandese, magari serve di creare un sezione per italiani, vedendo il fatto che c’e anche posto per tedeschi e inglesi…!
Invece voi italiani siete forti!!!!
