Doug, have you tried loosening up your grip on the bars, I have found that if I do not squeeze the bars and relax my sholders my ride is much more comfortable. Also I try to stay light and flexible on the bike, I'm constantly moving around, shifting my weight, I stand up every time I go over a bump or track, I ride my street bikes like dirt bikes, I'm all over them. I don't just plop down in the seat and stay, I try to support a lot of my weight with my legs. Sport bikes are way more comfortable than cruisers, it's hard to get a cruiser dude to believe that, but you are proof. Another really weird thing is that raising the seat on a sport bike has made it more comfortable for me. I have raised the tail on my last 3 sportbikes and they were way more comfortable. I'll post up when I raise the tail on my busa, check out the thread when I do it, I always get a bunch of opinions every time I raise one.
