I searched but did not find a proper solution...
Tenere XTZ 660 is really to windy and i rode quite a lot bikes before, and never felt so much wind turbulence and noise in my helmet already at low speeds.
There is some solutions, but no one explained which one is the best...
I found this on ADV for help...
