Hi Hubert, I did see back in previous posts on this thread that you had looked at getting one.
There is a message inside the helmet that the helmet should not be used on the roads in the US.
Not sure what US customs are like but my feeling is if it was imported as a display item it may get through.
I bought this from an online auction in Japan and had a friend carry it back to NZ for me.
The original retailer in Japan has sold out and I think these are only available on the second hand market.
I did managed to order the visor from the original helmet manufacturer " Airborn" reseller today though.

If you wanted, I could keep an eye out for another as I have seen one or two over time for sale in Japan.
Don't know how I would get it to you but we could work that out if it ever eventuated.
