Yesterday I purchased a Shoei RF 1000. Today I used it when I rode into work. First of all the ventilation is excellent. The wind noise under 80 mph is good. Over 80 mph is not that bad. The helmet is very light. Also, at speeds over 80 mph there is little head “bobblingâ€. I am really impressed with this helmet. I am glad that I took my Wife’s $300 and bought this helmet.
