ok maybe im just crazy but this keeps happening to me. i have a leather alpinestars jacket and an hjc helmet and a stock windscreen. now when i hit 90+mph the wind gets deflected right up my helmet and it feels like its going to fly off, not fun. anybody else have this problem. is it just that i should be tucked more at those speeds? idk

 

It's called Buffeting. Get a Puig windshield.

 

that happens to me anytime on the freeway and with no one in front of me. i just try and tuck down more.

 

like the double bubble Puig? would that help ?

 

I have a ZeroGravity double buble. It does help, but not as much as you would think.
When riding on the freeways at shall I say...higher speeds, I move back on the seat. In doing that, my head automatically ducks and wind resistance reduces greatly.

 

i just want one thats dark tinted and will help me keep my helmet on. ill try moving back on the seat tho thats a good idea.

 

Puig double bubble helped me a lot. Some may say it doesn't help as much as you think but after going from stock to the Puig the differnce was very noticeable.

 

double bubbles deflect the wind from your chest and neck to the top of your helmet, and would help your situation; i'd also make sure your helmet fits right, my helmet doesn't ever feel like you described, tucked, or riding straight up at speed, also, most helmets come with the neck flaps (not sure what its called); these also help keep some of the unwanted air flow and wind noise out of your helmet, but can also be kind of hot to ride with, especially if you live in a warmer area

 

im gonna look around for a new windscreen and try that. much cheaper than buying a new helmet

 

I'm reading reports that the double bubble will melt your dashboard when it's hot (like it is here in the southwest United States). I'd avoid it if it's going to cost you more money from the damage it causes.
