I'm running a BMW R100GS with a slightly modified solo seat and am considering possible seat improvements. What I have now is a stock seat with a gel pad added and some foam rubber cushioning between the seat pan and frame. I'd modified the seat mount to allow a little bit of extra travel as the pan moves up and down. Right now, I'm good for 300-400 mile days but would like to increase my comfort level and distance abilities. It's also very important to me to be able to get a foot down occasionally for off-road riding, (29" inseam) so the seat has to remain fairly narrow and low. I think if I had my druthers, I'd start with a bare pan then build it up and tear it down a few times using different materials until I really got it right. Don't think I really have the time or money for a project of this scope however, so it needs to come out pretty good on the first try. Anybody done any mods themselves, used any aftermarket accessories such as Airhawk or had a custom seat made that they're expecially happy with ? Thanks for any thoughts on mods, shops or construction.
