Or your helmet

 

lol no it is my helmet hahaha but could a gap in the pannels do that ????? cause i got a fair few of them

 

I would say so cos wind will whistle through any gap at the correct speed

Dont rule out something brake/transmission related too..

I would think wind noise from the bike would get alot worse at 30+ rather than going away..or being more noticeable at low speeds

 

my rear brake squeaks load when i use it that could be my probelm
