Ok sorry I was able to find a few things posted below, but I am still not certain.
This was originally posted by benphyr:
"here were a several iterations of the S30. Technically the Silvio and S30 versions could be taken apart and packed into airline luggage (barely). Here are the differences that I can think of:
Silvio 1: (the original performance Cruzbike)
-welded frame
-straight road components
-straight front triangle
-dual suspension
Silvio is the first Performance Cruzbike: Splits into Silvio as Road/touring machine and Vendetta as Race specific
Silvio 2 & 2.1:
-hydroformed frame
-curved front boom
-evolved into S30
In between somewhere people started occasionally calling some of them Silvio 3, or often called Silvio S30 in error - see
@Robert Holler 's message several posts below machines that still had the same Silvio 2 features:
-27 degree seat angle
-dual suspension (air head-shock thing and rear elastomer) - some swear it was great, some say gimmicky, some say never really worked - probably depends on the person, setup, type of roads you ride, etc.
S30 (has suspension/geometry changes):
-only sold for a short while
-basically same as original except no front shock, 33 degree seat angle, and different head angle
-slightly different paint scheme
-some say short wheel base good for maneuverability, some found head position hard on balance and short wheel base a little harsher
S40.1:
-no active suspension
-larger tire clearance and larger tires came stock
-rear triangle is welded frame triangle similar to "regular" bike
-wheel base lengthened significantly - improves stability (think loaded touring and straight line no hands)
-adds many attachment points for racks, fenders, etc. that were not on S30
S40.2 (current):
-1x drivetrain
-even more tire clearance and larger tires - up to gravel bike sizes??
S40.3 (Next generation - Hoping for a near future unveiling)"

And then this followup by Robert Holler:
"There was only ever ONE actual S30 production run. "Silvio S30" for the bike before the actual S30 was produced is nomenclature only - that was a "Silvio" production run that became in name "Silvio S30." The actual S30 had a solid front fork (and different head tube angle) and "S30" logo on the side, and a triangular hole in the rear gusset as opposed to the Silvio that has a round hole. If there are pics on the internets of one that have the "S30" paint on the side and a round hole in the gusset those are photoshop - the REAL S30 had a triangular hole."
SO, given that my bike has a circular whole in the rear gusset but does not have any suspension...not sure what that means :|
