Hello,
I have a Tour X3 and like it, my previous lid was an Arai also, they fit my headshape well.
I can't compare the X3 to the previous versions, but compared to my other Arai then there is a little more wind noise due to the style of the lid, but it perfectly acceptable. I normally use it without earplugs and i'm not deaf yet......pardon?? (sorry...old joke)
You can get visors from:
www.racevisors.co.uk
You can also get tinted pinlock inserts from them which is what I've done, why it gets dark, take out the pinlock and your back to a clear visor.
Nick.
