AGV SV S-4 Zebra vibrating at speed

[DucatiLussuria]

Anyone else have this helmet? I like the looks and fit, but at 80+mph the helmet begins to vibrate. I put the double bubble screen on my 748 just to see if that would help but the wind aims right at my head. If I go into a full tuck, the vibrating abates.

I emailed AGV a few days ago to see if they had a solution, but haven't heard a response. I haven't contacted the company I bought it from becuase I doubt I will get any response either: a discount ebay company.

The helmet is on tight and fits right. Anyone else with this problem?

Update: it looks like the vibrating is from the air coming up under the helmet. It was a little chilly on my ride this morning so I used a neck gator. This eliminated the vibration completely.

I've been using these for years. They really quiet down you helmet and keep you warmer in the winter. I've always used the standard version but I don't ride much below 40F.

I am considering this helmet - I've worn AGV helmets in the past and like them - from the reading I've done the fit on this is different aka a bit looser than the the Ti Tech I've been wearing in the past - have you found the fit to be standard ? Have you worn other AGV to compare the fit against?

Also, tell me about the built in sun visor? Your views and thoughts on that are appreciated - any other comment most appreciated also.

Thanks
