You can't be 100% sure your full-face will stay intact, either. I've seen a photo of a guy's full-face lid cracked open like an egg. The question is how likely is the failure of a flip-up design? Got any numbers on that? A couple of photos on the internet don't equal causality. There's hundreds of photos of Stroms that wrecked or broke down, is it a dangerous, unreliable bike?
Regarding the rest of the comments:
Noise - yes they're slightly more noisy. Almost helmets are noisy, by audiologists standards. As a blanket statement, it doesn't take into account that some flip ups are quieter than some full faces.
Weather - again, blanket statement. My Caberg Trip keeps weather out perfectly, better than the Bell Star it replaced. So, again, poor argument as a generality.
Weight - need I even say it? Not all modulars are heavy. Not all full faces are light.
Can't ride with the chin bar up - why is this an issue? More to the point, why would you consider this a downside? Of course you can ride with the bar up, you just accept that it's now an open face helmet. If the "chin bar always breaks in an accident" myth is to be trusted, it's a moot point right? Absurd complaint, honestly.
Balance - Mine is balanced....or maybe my head is crooked. Whatever.
