How long have you had it and do you ever ride with the visor open? Mine has an unbearable high pitched whistle with the visor open. I'm trying to find someone else to confirm so I can figure out if mine is a defect or design flaw.Shoei Rf-1200 here. Noise is tolerable, especially since I wear earplugs. Was going to go solid white for visibility but this was too sweet to pass up.
