I have a 2016 Road Glide Special. i have a high pitch hissing noise that gets louder and higher in pitch as speed increases and when i hit the front breaks the noise get much louder. is this to do with break pads or the front Wheel Bearings?? its almost like a rapid High Pitch Clicking noise that gets faster and faster as speed increases. is it the ABS Magnetic censer inside the wheel Bearing...do the bearings need to be replaced?? or do i just turn up the Music so i don't hear it? But I don't like the noise if you say it's some kind of normal... i want it to sound smooth and be smooth. as it is it sounds like something is not right or is wearing out fast and or break soon.
