Driveshaft PX 200 LUSSO 2ºX COSA 200 2º


I would like to make a question:

We know that the Cosa 2 cluch have 8 small springs and different comparate the PX models.

But, the driveshaft of the Cosa 200, is equal to the PX 200 Lusso 2º? The driveshaft of PX 200 Lusso doesnt have the "ring" as the PX old and the others old vespas as rally.

Is the driveshaft equal to PX 200 LUSSO 2ºand Cosa 2º?

In the description of SIP Website, i can presume that is the same.  This question is for, the wish of a tunned vespa

Best regards
