I don't complain here much, BUT I have had nothing but trouble with my Arai.
1. When changing my shield, the side cover broke off, rendering the helmet useless. Now you can blame me for being far to powerful, but I never had this issue with my Shoei's.
2. Side cover cracked again, helmet rendered useless. I don't know how it cracked this time, probably my fault. Never had this happen with Shoei.
3. Last Saturday when pulling up my shield, the little plastic tab snapped off, now the shield won't snap shut.
4. Can't buy on-line.
5. Parts are hard to come buy on-line or otherwise.
6. Noisier than my last Shoei.
Now I know I've offended Arai lovers out there, but I only offer the truth. Arai just hasn't worked out for me, I'll be going back to Shoei. I know all Arai helmets aren't crap or they wouldn't sell so many. Besides, my chin molding hasn't fallen off yet!
Oh, I have a RX-7RR4 a little over two years old.
