Crap.... It's not nice to make me choose between them.
Ok, assuming the things that should be corrected on bikes relative to their rider are correct or corrected on the Road Glide; windshield height, handlebar position/reach and seat. Assuming those are all equally dialed in to the rider on each bike the Road Glide is a more pleasant ride going down the ride.
Just going straight down the highway I can't say the difference is huge. But it is real and it is noticeable. A more dramatic difference is the handling though. Without having all the weight of the fairing, radio, harness and other electronics on the bars going from one bike to the other makes the Road Glide feel amost nimble (or as nimble as a hog that size can be).
As Doc mentioned with the lowers on and tucked up close to the fairing not a lot gets to the rider. It is a nice, clean, non-turbulent and surprisingly quiet ride. It's not that the SEEGs are completely competent to take down the highway all day long. They are. Especially when setup accordingly for the task. It is readily apparent, however, that the RG is even more suited to the task.
Don, I have riden two Road Glides in my life and I would agree with all your statements based
on my limited experience with them. I enjoyed the nimble feel and air management a lot more
than my SEEG. I also felt the RG more pleasant to ride in all areas of riding. I still like the look
of the batwing better but I feel a SERG will be in my future. Of course it has to be the Yellow
one and I guess I will just have to buy the lowers and tour pack extra. They probably won't
make a Yellow one next year.
