WOW!! I am completely shocked that this thread has gone THREE pages and not one mention of Scorpion Helmets. Completely surprises me.
I have had a Scorpion EXO-700 since July last year and I am completely impressed with its quiet, ease of glareshield removal and its low price. The helmet was rated #2 behind the Three times more expensive Arai by JD Powers consumer ratings and their own in-house testing.
In the 760 miles of rain I rode in earlier this month... the visor didn't fog ONCE! In fact... it hasn't since I bought it new. The liner is extremely comfortable and it hasn't lost its fit.
Scorpion has announced their new line, the EXO-1000 helmet that has air bladders like a NIKE pump shoe. It uses the same type of technology to insure a perfect fit and surround each time you wear the helmet.
Oh... did I mention their kevlar helmet is lightweight too? All for the lower price of $150 for a non-graphic helmet.
I've tried quite a few others and I like that the Scorpion never bobbles at high speeds like the ICON does. Even some of the Arai helmets I have tried still buffet at speeds over 160+. When I was shopping for a helmet, only the Schuberth was quieter than the Scorpion, but it better be for 3-4 times the cost. Considering the miles I ride, I wanted comfort, safety and function. Cost really wasn't the option.
