Interesting thread, I will sometimes get an excrutiating pain after maybe 3 hours in the saddle. For the balance of the day, no relief. Ear plugs make it worse. It seams like it comes from some harmonic that is caused with wind. I ride a 1200GS now with Givi windscreen. My open faces hurt so bad I don't even use them. Full face Shoei X-11 is better but still will have that ear pain. Becasue they were quieter I actually tried the Schuberth, the ear pain is non-existant with that helmet. Anyone else had that experience? Anyone have any idea what the deal is?
