Hi guys !
Is there any crankshafts with 85mm rod and 44 stroke ?
Is there any rods that fits right on ciaocranks ?

I believe simonini still sells them.

44mm stroke, i dont know about the length of the rod.
The normal rod for vespa is 87mm?
Yes, and as far as I could measure this 44stroke simonini crank has a 87mm rod.
The diameter of the crankshaft is bigger than normal: 74mm instead of 70mm so you will need to mill your engine (except for simonini engine)

Thanks for your help guys !

Just use a 2mm spacer. This will overcome the length of the connection rod and will make use for the Minarelli Cylinders.
Also keep in mind there is an 44m stroke crank from Mazzucchelli, but i don’t know the measurements of these cranks.
