nice one regie, had used filter skins on the race bikes in the past and they certainly help, in one day on the isde poland i changed 7 filters in one day![no skins as team gasgas did not trust them]very sandy/dusty. your fellow country man matt fish was on my minute, it was so bad and he kept filling me in

pity we dont get the foam filter on the tenere here, though it would even save the paper element in dusty conditions.though looking out the window it's a large bore head high snorkle required!
