Will air deflectors on my 08 street glide prevent air flow from coming up under the full face helmet of my passenger.

 

well they sure helped me w/ the wind coming past tank..

 

The baffle under the forks helped stop a lot of wind coming over the tank on my Ultra. Don't think it would affect the passenger much but haven't heard of passenger having buffeting issues unless they were wearing a helmet that was too big.

 

I had the bakerbuilt air deflectors on my 04 ultra and my bride wants them added to the 09. She says they took all the wind out of her face.
