You guys and your seats kill me -- It ain't the seat it's the bike
Change it if you like it just won't make and difference except remove the excess lump in your left back pocket. That's why the aftermarket seat replacement is so strong. 
Wayne...for the life of me, I don't understand how you can say this...

It hasn't got anything to do with the bike, but everything to do with how the bike fits each individual ass, and how well the seat supports a given ass. It hasn't got anything to do with rationalization, justification, or any other cognitive dissonance issue, and everything to do with whether my tailbone is killing me after 100 miles, or after 700 miles, or not at all. I could not sit on the stock seat for more than 150 miles without EXCRUTIATING pain, and the Corbin does not cause me that pain. It hasn't got anything to do with my wallet being thinner either.
I had to change the seat on my Ducati too, and chose a Corbin...much improvement, and I rarely rode the bike more than 150 miles at a time. Perhaps a Wing or Beemer seat might work perfectly for me, but from what I've seen, they would probably be too wide to fit me well.
I've also changed my bars out, because the stock bars did not fit my riding position well...my wallet is lighter from that too, but my shoulders tell me it was money well spent. It's all about the ergonomics...like saying a bench seat out of a 48 pickup truck will work well for everyone out there...I mean, I COULD sit on an applecrate bolted to the floorboard of my car, but choose something a little more comfortable.
The stock seat, handlebars, backrest, etc, does indeed work well for some people, but not for all. You ride a lot of miles, so I am glad that the stock seat is working well for you, but making a generalized, sweeping statement about people wasting money on aftermarket seats is going a bit far, IMO, and I do not understand how such a statement can be seriously made.
