So, I've used the MRA touring screen for about a month now (I was off the cycle due to a broken collar bone, subsequent surgery, and healing), and I'm ready to weigh in.
My .02: don't bother. The OEM screen is fine, there's no additional benefit worth this price.
I tried the touring screen, and did not get much of the air stream off my helmet. I did get some small additional wind off my chest, but not my helmet.
So, I bought and installed that X-screen thing. Another buck 'n a half for that silly thing. I played with that trying to get air off my helmet.
When it's fully angled toward me, it lifts air right into my helmet underneath, just what I wanted to avoid. When it's fully angled upright, it puts the airstream front 'n center on my face shield.
This was all a waste of time and money, for me.
I'm 6 ft, 0 in., I have a basically stock OEM seating position (lowered the pegs an inch). It's not like I'm super tall, hanging out in the wind.
So, your mileage may vary, but I wish I had my cash back.
I'm gonna live with it until I decide what my next ride is.
