This is for all of you who love to have everything original, even helmets:
The system 4 BMW helmet cannot be bought in the US due to that BMW has not yet applied their helmet for DOT approval. However, here in Costa Rica, the Helmet sells well, and any one of you or four friend that come down here for vacation, can visit the dealer and buy/order a system 4 helmet of the color of their choice. one thing to note: they are Extremely expensive, but they are excellent in fit and finish. They go for $600 Dollar each. A Suiss friend, who lives down here, told me that back in Europe they cost about $500-550- Dollars each, so the price diference is not significant. If you have any interest, just e-mail for more details and info.
