I have the regular windscreen hardware with an extra tall Cee Bailey aftermarket replacement. It's tall enough that I look through it at 6'2", if you choose one that tall that you will look through it, be sure it's optical quality. Cee Bailey makes aircraft windows so the acrylic is good to see though without scratching easily and distorting vision.
The R3 is such a large bike, even oversize windscreens don't look out of place on them.
Maybe it's 'cause I'm old, but I really enjoy having a big windscreen now. I never had anything between me and wind until a couple years ago, but decided to do it after getting smacked in the face with a square foot of truck tire recap tread. It's been a pleasure to ride behind as well as a safety issue around here with all the **** on the highways.
