just to compare, I ride a 300i downtown 2011,. I can ride all day at 75 mph. passing up to 85 mph. tops out at 90 mph. that is on the speedometer,. on long trips I gas up at 200 miles, if I know there is gas bars handy,. longest ride was 500 miles one way,. the 200 miles was a good time to rest and strech,. for ten minuits and test the modded seat for comfort, raised the seat 4 inches and cut the seat back about 5 inches, now I can strech the legs out a little, but it puts my head up above the givi sheild, with the sun shine there has to be some rain,.
