I have loved and currently continue to use ARAI helmets, however, the side shields suck, they are noisy, and I can't 'get it' to change the lens'!
Years ago, in the mid 80s I had BELL Moto III M/X helmet, and a BELL Star street bike helmet; the best of that day. BELL went into the toilet soon afterwards and made crap, and no my M/C lids.
However, I just waded back into the BELL world! I am impressed with the fit, finish, quality, and comfort of their new model, this is the lid I got, it fits really well, better than my ARAI RX-7, seriously!
One thing about business is that you have to constantly change, adapt and be innovative. Sadly, ARAI has not done this to keep their brand fresh and new; they still make a great lid, but, the $$ is really steep for that make. I don't think the new BELL models are cheap and inferior either, I am sure they are NOT making money yet on these lids. Remember Hyundai cars in the late 80s and 90s? Cheap and shitty, then, they got good and expensive! I don't think this BELL lid is cheap in quality, I think it's pretty good.
