Iím afraid I agree with the OP. Iíve had SC seats on two bikes and my experiences were similar to his.
I know and like the guys from SC and they did their best to fix the seats, but after two tries, I gave up and sold it.
Just like Corbin seats donít work for everyone (too hard), SC seats donít work for some.
I have a couple of seats for my KLR today: A Sargent and an Ultimate Seat (kind of a Corbin seat but more $$$$) and I like both an awful lot.
Keep experimenting, keep trying new ones. Eventually youíll find the perfect fit.
There are two rules for being successful in life.
Rule 1: Never tell others everything you know.
