The on-the-fly damping adjustment is mostly a marketing gimmick since the range of adjustment is actually very narrow and the middle setting seems to provide the best ride over any distance on any road surface I have found (and I change the damping constantly trying to find the best ride).
Interesting that you would say that, as that has not entirely been my experience. But it may be the way that I am using it
There are 12 unique programmable settings. Soft, Normal, and Hard at each of the 4 pre-load settings (1 up, 1up w/ bags, 2up, 2up w/ bags). I have programmed all 4 of the Soft positions to -3, all 4 of the Hard positions to +3, leaving all of the Normal settings at 0. There is quite a noticeable difference between Soft -3, Normal 0, and Hard +3 while riding down the road.
As you know, the roads in New England are some of the most scenic, but are some of worst in the country in terms of smoothness. Many seem like old cow paths that were just paved over, and every winter they heave and buckle with frost heaves that never fully recover after the thaw. Running at 1-up Soft -3 (when 1-up) the FJR feels nearly as smooth over the rip-rap as my Vstrom does. But when I do hit some good pavement with a few turns in it, switching it up to Normal or Hard makes a significant reduction in how much wallowing I get.
