hi i have an arai chaser x in competition red and still in really good condition, which cost me about £480 with the dark visor , it has a clear and dark visor , i have just seen a couple of small marks on the black part of the helmet maybe stone chips but i havent worn it for ages so only just noticed on cleaning it , as i prefer my hjc 11 , so it is just sat in my cupboard , so any ideas on the value to sell , thanks.
