Modern Vespa

I've tried searching but cannot find the exact answer to my question. The Super and Supersport are basically the same bike, so I'm sure the seat pan is identical to both. However, is the only difference between the seats that the Supersport has a ribbed cover instead of plain, with a different contour on the piping? Or is it a different profile completely, i.e. different foam shape as well? I can't figure it out by looking at the pictures of each.

Thanks

Same seat aside from the ribbing and color piping.

Thanks Kevin
