These are an acquired taste.

Been a long-time fan of modular helmets, having had two LS2 FF324 before but I find the visor release latch to be bloody fragile and it's a royal pain in the arse to remove the visor without breaking the flimsy latches. I've broken them in both my helmets, and the drop down sun visors have become stiuck -- they're due to be sent back to LS2 in Penang next week for repairs when I make a run back to USM to get my graduation gown for my convo.

So when I moved up to an adv touring bike with a big windshield, I got a Scorpion ADX1 and an HJC C80, both dual-sport modulars with a peak & elongated chin bar.

Bought them because they use simple metal screws that hold the visor in place, a far simpler & better mechanism coz they won't break like the silly latches of my LS2 FF324s. Not exactly of the quick-release nature, but I never had the need to remove my visors in a hurry anyway so it doesn't matter.

These are fine when u have a big windscreen coz the peaks won't catch in the slipstream. The original purpose of the peak on off-road oriented bikes is that if you tilt your head down a bit they can keep the muck from the rooster tail left by the bike in front off your visor. I don't ride like that, but I do find the peak to be useful keeping the worst off your visor in heavy rain.

I like the elongated chin bar as it leaves plenty of breathing room between your mouth and the chin bar, allowing my Cardo mic to slip under pretty easily when I close it down. They also tend to have a bigger viewing port, so together with the additional room behind the chin bar they make the helmet less stuffy when you have to ride in slow traffic at noon. Just opening the visor is often enough to let in plenty of air, instead of having to lift up the entire chin bar.

Between the C80 and the ADX-1, the ADX-1 is clearly my favourite of the two. The only drawback is it isn't P/J rated unlike the C80, although the new ADX-2 addresses this issue. Not much a problem to me coz I have hardly had the need to ride with the chin bar up anyway coz the viewing port is so damn big.
