justcoolen, Apr 13 2006, 10:52 AMHow would the Icon Domain compare to Arai Quantum, or the Shoei RF1000? Regarding venting, weight and wind noise.
I am not in a good position to make a comparison. I have a history with Shoei helmets and have not ever found an Arai to fit very well (for me), much less owned one. As for the RF-1000, honestly I don't know. As I mentioned, I have replaced a nearly 10 year old X-8 Air. That comparison I can make.
Weight feels about the same, but I haven't put either on a scale for accurate comparison. The foam thickness (and overall physical size comparison) is thicker in the back portion of the Icon (more protection for the back of ones egg is my guess), and that make the overall helmet slightly bigger. I rode a short test distance near my house with my old X-8 Air. I took notice of feeling ventilation on the top of my head, whether or not I had to crack the faceshield to prevent fogging and tried to notice the ambient noise levels during acceleration and while idling. When I got home, I took off the X-8 Air and left my earplugs in. Switched helmets and rode the same route making all the same kinds of mental notes I did just minutes before.
My unscientific conclusions so far are:
Weight, feel and comfort - very similar to the X-8 Air, not a lot of cross wind during my evaluation (still ongoing), but very comfortable. More room around my ears so they don't feel as scrunched up.
Fogging - Well they say it is fog free. Not so, however, when moving it does clear breath fog very much better and quicker than the Shoei. I had to crack the Shoei when stopped, not so for the Icon.
Noise - audio levels from inside the helmet seemed about the same between the two. I did not notice any difference (I alway wear earplugs).
Ventilation - My X-8 Air had been the best venting Shoei I have ever owned. The Icon ventilation was far superior to what I had been used to. I have never owned nor ridden with an RF-1000, so I cannot say what if any difference there may be.
Having read a recent article that went behind the scenes into the HJC factory, I gotta say that they have come a long way very fast. I do not have any facts that Icon helmets are produced by HJC, so I'll just say that if this is the case and after what I read, I am not worried about my egg. DOT and SNELL 2005 rated and more affordable than the top of the line Shoeis. SNELL is not an easy endorsement to get, so it ain't junk. I have nothing bad to say about Shoei. They have been very good to my egg over the years. I have always felt that one should buy the best protection that they can afford. I can say with clear conscience that I feel good about my purchase and the new home my egg resides in.
