I have a 300i DT. and the same problem I cut the dome out of the seat were the helmet fits up into it, sitting on the seat feels much better, as I can slide back a couple of inches, and I rebuilt the foam higher by 2 " and cut off some of the foam off of top of seat back, so it is almost level, from front to back,now I can see right over my givi wind sheild, I have not gone on a long ride on it yet, but it feels good on short rides, it will be a while befor i do snow & ice on the road & im 79 years old, so I try to preserve the old bones ,. merry Xmas everyone joe
