SOME SIZES NOT AVAILABLE UNTIL THE NEW YEAR Arai CK-6 racing helmet, CMR Snell K2015 approved. These helmets are brand new and come with a FREE genuine visor plus suitable rear spoiler as favoured by major helmet painters. Always comes with a clear visor, but if you select no additional visor this is all that will be included. Rear spoiler requires fitting should you wish to fit it, simply pull off the back vents (they're glued on) and stick on the rear spoiler (with supplied fitting tape). Select your required visor, these are genuine iridium visors which we've found to be the most long lasting visor on the market. Not the smoked ones are not iridium. To find your size, measure your head above your ears, round the head.
