New Helmet - RF1400

[Grumpy Goat]

...
So, I actually had the Arai staff fit me in a Corsair X which is a great helmet, but gets few demerits from me.

1) While it has a lot of air vents, they must be completely closed to avoid generating noise
2) The height of the eye-opening is about 8~10mm less than my old X-11 or the new RF1400, I have to tilt my head more to see the dash or tank bag. The round shape (less fore-aft length than the Shoei's) seems to compound this problem (i.e., it's hard to look down at your shoes)
3) It's the only helmet I've ever suffered a stone chip. Filled it with auto touch-up paint and clear coat.
4) The chin guard / curtain must be installed to minimize noise.
5) The shield has no intermediate openings.......just open, closed and loose

So, the Arai is my cool weather lid

I am not surprised at Items #1 and #4 with regard to noise. In order to minimize noise in all helmets all holes need to be closed - as a motovlogger I am particularly sensitive to this. Helmets that flow a lot of air (such as the Shoei RFx helmets) can be noisy until vents are closed. Surprisingly, the biggest culprit for noise is the opening at the bottom of the helmet - chin area and also around the neck. If those areas can be plugged the biggest dropoff in noise will be seen.

One of the things that I don't like about Arais is the small eye port, which your Item #2 notes. Helmets marketed for racing, for instance, will have a larger eye port since the use case is such that the rider will be in the tuck position more than say a helmet targeted more for the sport tourer market. Maybe the Corsair X is intended more for the more upright rider ... just guessing. A 30 second search did not provide conclusive evidence in that regard. Arai also has their own design philosophy (round helmet, etc.) which could also dictate smaller eye ports. Interesting that this is the only helmet in which you got a stone chip since the round design was intended to allow for more glancing performance when the helmet is doing the striking, as opposed to when it is being struck ... which should be the same / similar but in reverse.

I also dislike lack of detents on the visor (Item #5) and for a premium helmet that is not acceptable. It is not as if the lack of detents enhances safety in the design.
