All GL1100s came with the same basic seat, although the Aspencade's was a bit fancier and you could move it fore & aft without loosening the bolts as was required for the Standard and Interstate models.
When the seat on my 1100 split we were broke so I bought some vinyl and re-covered it myself. By the time it was starting to look tired we were a bit better off so I took the spare seat I had acquired to be done by a pro. I wanted the bump moved back as far as possible but he could only move it a bit because of the step in the pan.
It's not a huge difference but it does make a difference.
I don't know if these pics will have any relevancy to the CX500C but here's the one he did (left) and the one I did (right)
old seat
"new" seat
