At 6'4" I need a taller screen than BMW offer.
This option is much better than the one my RT came with, but it still allows some air to hit me at the top of the helmet (better than straight in the face though!)
I do end up looking across the top of the screen which is not idea, a bit higher and I could look through it.
On my 2018 RT I manged to find a screen with a bit more flip so that I was out of the air flow and not looking across or through the screen.
However until I get a R1300RT (at some point in the future) this screen will certainly do.
