I purchased the zero gravity touring windscreen for my 2012 fz6r.
I'm 6.4 (192cm) and it helps a little bit. It still hits my helmet but i'm experiencing less turbulence.
One thing i did not like about the windscreen is that they put this stupid zero gravity sticker on the bottom and it does...
picked mine up in december, 2012 model with 2200 miles on it. Paid $3000.
It had some scratches on the side but it's my first bike and I dropped it when i got home after picking it up so luckily that didnt matter at all..
