I am 6'2 & use a Puig double bubble which over all is very good but I DO get head & shoulders buffeting on the motorway unless I tuck down.
Generally speaking, nothing but a touring bike with full screen will stop that, but the screen you've found looks like it should do the trick.
It seems like a good & tall screen without going too wide.
I've not seen it before, is it made by/for the eBay vendor?
Purely personally speaking, I think that large screens look wrong on bikes like the Fazer, but I sympathise with the need for a decent screen!
