David, several years ago in Bend, Oregon I ALMOST bought a BMS unit for my K12GT (if they would have sold me their ‘show n tell’ unit right then and there).
It was shaped like a big leather covered tractor seat and it felt so very comfy. But when I got home I ordered the Russell Day-Long and am not disappointed at all.
I am looking for some improvement for the F700GS to ride maybe 400 miles in a day as a max. And I think I’m gonna try the SEATCONCEPTS unit.
Thanks for your input.
