If I want to mount a minarelliclutch , does it matter what gearing I have , or do I need malossi ? I heard I need malossi but I’m insecure.
I will use the minarelli clutch mount axis.
no you can use 1-10,5 gearing also, but you need a drilling machine to turn your engine on, because the minarelli clutch isn’t made for a running start!
Depends how fast you want to go.
Stock simonini 2007 engine + “25kph” gearing (1:10.73) + peugeot fox clutch + citta wheels = just over 100kph. A ciao may reach 110-115kph and that is with relatively low revs compared to a fast scooter cylinder.

Can you recommend any faster gearing ? Except for malossi.
If you want to use a Minarelli clutch. You had to make your own gearing anyhow. So you also could make the choice of using a 1:6,5 ratio from what we call “bromvertanding”. But in my opinion this is somewhat to long, even for the faster engines like a Simo 2007.

Even so it all depends on what you are looking for? I thought the Malmby meeting was only a drag strip, but i see now they also going for top speed.

Long gearing will mostly harm acceleration from a standing start during the time the clutch is slipping. (this only applies to a good, stable variomatic setup, not the standard junk a vespa is equipped with)
I’ve found the 1:10.73 gearing on my citta adequate (101kph), I think on a ciao with 17″ rims and 13-14.000rpm engine it will be blisteringly fast and therefore more than adequate.
However I think you should use 1:9 malossi gearing for a couple of reasons:
– It greatly reduces the rpm of you clutch bell reducing the chance of fatigue of the drive axle
– You say you want to use Minarelli clutch which has bigger pullies compared to the fox clutch I used. This reduces the overall gearing and therefore probably the top speed
– Malossi gearing has straight cut gears which has slightly higher efficiency than stock helical gearing
– You are probably a maniac so stopping at 115kph is unacceptable :lol
– There is sufficient power to get you off the lineDo not go for 1:6.75 or even 1:7.5

Home made engine dynoThank you for those answers Arvid but I still have a few questions.
Do I need vario axis to modify to minarelli ?
Is there a roller cage in the hub for the axis that I need to replace to a bigger one that fits the minarelli axis ?

The minarelli axle is not a drop-in replacement. You need to combine the front halve of the minarelli axle with the vespa axle.
There are multiple way’s to do so. Multiple people at this forum did it in different way’s
– Me (http://www.vespa-ciao.nl/page.php?id=294)
– Virgil
– Herrflick
– Javadand probably some others. My axle configuration broke after +/-3000km and my second axle did too. Javad’s axle is still in one piece however he doesn’t have a 100+ kph setup. Herrflick’s axle broke because the fabrication was not done properly.

I figured I would have to do that way , I am going to have splines on the minarellipart instead of just flat.
Also with the drivebelt , I read pagano’s bravo thread , he said something about minarellibelt on ciao vario , I didn’t understand what he meant tho.
What setup did you have on your 3000km axle since it held so long ?
I used a stock 13mm citta variomatic v-belt because I used a Fox clutch which is designed for 15mm belts (and accepts 13mm v-belts).
During the 3000km’s I had a simo07 setup, a setup of tuned piaggio parts (exept for exhaust) which reached just over 80kph, and a side-inlet DR70evo setup capable of just over 95kph. However I’m not a complete idiot (no helmet) so normally i drove less than 60kph

How did it break ?
First axle: The force fit of the 10mm pin between fox and vespa part gave away, so no torque could be transferred any more (axle still in one piece)
Second axle: Weld between both axles gave way, screwtread between both parts broke. Axle broke in 2 parts. Clutchbell passed me at aprox 80kph :lol
