Can Off Road helmets used on tarmac?

I'm happy with the N70,it's just the ear thing...and that only when I wear ear plugs,which should be all the time eh? I might have a look at it and see if I can hollow it out around the ear 'ole part,just to take some pressure off that area.With my MX helmet and ear plugs in I can hear my phone ring,which freaked me out when I first heard it on some lonely back road....so a lot more ''input'' when wearing a dirt helmet,more in contact with your surroundings.

I had an N70 for a while. My only problem was that the helmet felt to shallow, my chin felt very exposed. I am now looking at an Arai TourX.

I had a lot of ''chin chill'' with the N70 when the beard went,and have half a doz bits of gizmos to help,but getting rid of the screen and getting airflow to the helmet helped the most.
