I dont find I get any more or less noise and it breaks up the wind on my chest so I like them.
Also like watching bugs hit the windshield and not my jacket.
I want a even bigger one .
Depending on how you angle it , I find it alleviates my helmet turbulence.
Now when I used to ride bigger cruiser motorcycles I had the huge Memphis fats windshield and
depending on height it could add helmet turbulence , but thats at fast highway speeds.
