Brian,
Have you ridden the SERG long enough on any one run yet to have an idea how the seat is going to be?
Don, I ran 122 miles yesterday with one stop. Not a huge distance, but long enough to figure out I'm not squirming around near as much as I do with the SEEG. I think it's gonna be fine. I am running the backrest on this bike since there is not as large a bucket with this seat as there is with the Comfort Stitch seat that I have on the SEEG, and it seems to help quite a bit with the comfort factor.
I am really enjoying this bike. The fixed fairing is a bit warmer to ride behind than the SEEGs with the Kuryakyn Dragon Wings, so I can see why the lowers were off when I looked at the bike, but it's really a sweet machine to roll some miles on.
