Ever since I started riding some 50 years ago, I have always had trouble staying seated for very long. I suffer, as many men do, from "totallackofbuttpadding". Even on my TriGlide with its cushy seat and a sheepskin on top of it will have me squirming in 30 miles.
I bought a cheap gel pad for an office chair on Amazon and it arrived today. I trimmed it to fit my seating area and put it between the seat and the sheepskin....AAAAHHHHHH relief....went out for a hundred miles accross the desert and through the pines and was just starting to get squirmy at the 95 mile mark.
It does sit me up about an inch, and due to the honeycomb construction, I feel like I am moving around on the seat, but got used to both of those things in 15 minutes.
All in all $15 and 15 minutes well spent.
YMMV
