I have just bought an AGV K 5 and they are not noisy. Granted it is not as quiet as my Schubert but it is a lot better than an x lite People can praise Arai but they are not worth the money they charge
Depending on what you do to it yes - paint it matt black, you won't see out of it - leave some eye holes
I have an old OGK FF3 from Circa 2002 ish :Wideyed: it's been a good helmet but is certainly long requiring replacement. I don't throw money away on style icons when other products are just as good if not seemingly better in some areas
Schuberth was my favourite helmet cost me £200 same as my Arai My arai was worth the money saved my head in my accident My Schubert went bang when it fell off my bike
OGK I remember trying one of them on and came to the conclusion you needed a particular shaped noggin to get a good fit
