I’m on my second 1600, having owned one since they were first released.
Every rider is different, either by height, the way they sit on the bike, the helmet they wear, whether or not they wear earplugs, whether they are prepared to accept some buffeting or wind noise is a part of motorcycling or if they think it’s only great if they sit in bubble of nothing.
From 1000’s of miles, I have found that where I sit the standard, near enough infinitely adjustable screen (which I think is fine) might differ depending on the mood I’m in, the ‘cleanness’ of the air (the air on busy motorways is more turbulent than say an alpine valley at 08:00 on a summer’s morning) the speed I am travelling at, any crosswinds and God knows what else.
