It`s a bit noisier than my old Shoei, but not bad. Only thing I hate in it, is the attachment system of the visor, those screws... I like`d very very much about fast system in Shoei.
All the rest is fine, looks good, large view and so.. And good looking too.
When I was back in North Wales I called into Colwyn Bay Motorcycles where they had a plain (the best - none of that shellsuit stripy nonsense) grey Tour X at £299.
I quoted the online price of £265 which they agreed to match so...what could I do...had to have it.
A great helmet, not too noisy but it does catch the wind a bit on the motorway when you look over your shoulder at "enthusiastic" peeds. I find the best technique is a sort of look down and around motion.
I found that the sizing equated to other Arais pretty much - I have a large RV and the large Tour X fitted too.
