I agree it's certainly not the best seat I've ever ridden...I can't remember which mag wrote this, but I feel it describes it best: Tends to "separate the cheeks" a bit too much. But I've never had a sore tailbone from riding it. Just an extra skidmark or two (hence my signature). Ok...maybe that was too much info to share.

But anytime it's gonna be rough I just stand up...which is the benefit of the riser on the Dragon package which you apparently don't have. Stand-ups are real easy and natural with the taller bars.
Brainstorming possible solutions: A Boss seat comes to mind. But stock seat isn't bad enough for me to consider the expense...you may feel it's worthwhile however. Alternately an upholstery shop could probably do a nice job of removing the seat cover, changing the foam out for something more to your liking, and putting the seat cover back on. Probably less expensive than a Boss seat. Option 3 is to put a taller riser on your handlebars so you can stand more easily and more frequently, and not take direct hits to the can...
Good luck!
