Re: More on Shoeis
I cannot give a report on both, as I do not own both. I daresay, not many on this forum own or have tried both, so you may be at the mercy of the tabloid research connection if you want direct comparisons.
I have a ZII and an Arai Signet. For my shaped noggin, I find they both fit very well, and I recommend both. However, YOUR head and mileage may vary. The first priority is to find a lid that fits your head shape. If you don't have a well stocked local dealership(s) now is the time to visit the annual motorcycle show coming to your area and try on everything the vendors have in stock!
The ZII has become my primary helmet, but not by much over my Arai. It is lighter, the shell is more form fitting and ventilation is good. The Arai is heavier by a couple of perceived ounces, not anything to complain about. Ventilation in both is good. Noise is not an issue for me as I always wear earplugs. Peripheral vision is better with the Arai due to a larger eye port, but not of any significance.
As I write this, I have become aware of the only reason I prefer one over the other, and that is the graphics. They are both excellent, but I like my ZII Slash just a bit better stylewise!
However, when it comes down to actual use, I alternate every other ride with the helmets, so I guess I like them equally both.
My advise is try the ones on that you are considering and walk around the store for half an hour wearing the lid. If you are happy, then buy it. Support your local dealer the first time. After that, you know what model and size works for you, and you have other options to consider.
