I can kind of understand why people put stereos into their motorcycles... but it never really made sense for me. Too much road and engine/pipe noise to actually enjoy the music - and a disturbance to those around especially when you pull up to a stop. Several years ago I bought a helmet with bluetooth speakers and a microphone built in. It has touch controls on the outside left of the helmet for volume, or skip, or answer/hangup so your right hand stays on the throttle. I can stream music or radio from the phone and control the volume and even answer calls. I didn’t find it a distraction though actually holding a conversation while cruising was not a good idea for either party.
Being practically deaf, I don’t have that problem.
I have to turn off my hearing aides to keep them from squealing from the wind noise!......................
