So my bike came with a Corbin seat when I bought it, but the seat's contours didn't really fit the bike and made it a little uncomfortable. So I sold it and put back on the stock seat, which is the most )(#$*)@#(*$ uncomfortable "plank of wood" any bike manufacturer makes.
I got the number of an uphostry guy -- company name AquaTech (719.590.7011) in the Springs, and then ordered my own gel pad. It is 3/4" thick. Its at the bottom of this webpage: http://www.waynesvillecycle.com/motorcycle_gel_pads.htm
Even after paying someone else to pull off the seat cover, carve out the foam to put the gel pad in there, and put everything back together, grand total was under $100. I finally got to test it out on my 70 mile ride to work this morning. MUCH more comfortable than the stock seat.
So there are other options out there....
