What facial injuries are sustained w/ full-face helmet?

[RedShift]

After reading this thread I'm again thankful that I've never had an accident.

Although I have a full-face, I'm now of the opinion that it's at least one size too big for my head.  My evidence comes from watching AMA races on TV.  Interviews with their helmets on show their cheeks are pressed up towards their eyes.

I mention that as a lead-in.  Apart from the odd MC video, the only accidents I've seen at any speed have been during racing.  When a High-Side spits a rider off, they often land or slide with significant insult to the head area.  Most of these guys get up and often can't see through their visors, but after they shake the gravel out of the helmets, they seem to be in good shape (face-wise).

So, I'm thinking that perhaps helmet fit has a lot to do with potential injury.  My next helmet will be a lot tighter.  I figure that rapid deceleration is the main cause of injury, so the tighter the helmet (and thicker the pading) the better the protection.

Serious facial injuries are a rarity with full face helmets PROVIDED the helmet fits properly.  One problem is that a lot of guys buy a helmet purely to keep from getting pulled over and fined, so any old thing that feels comfortable will do.  Another problem is that people buy a hat over the net without ever trying it on.  If you must order a hat online, at least have tried on that make and model for real.
For the helmet to protect it must fit properly.  Unfortunately a lot of riders (and shop assistants) don't know how to fit a helmet.  When you first buy it it will be tight.  The padding will settle a bit and be more comfortable over time.  The chin strap should be positioned so you don't feel like you're choking, but must still be firm.  Once the helmet starts to feel loose (as they all will eventually) it should be turned into a garden planter.

One way or another, a dodgy helmet will contain a vegetable of some sort.  Once it's loose it does not protect as well.  It may be overkill and, yes, they aren't cheap, but you only get one head.

Part of the reason for my helmet rotating was that is was too loose. Hitting the rock at around 50mph does help much either. My face was a little swollen in that pic since it was taken about 2 weeks after wrecking. Plus I broke my left collar bone from the helmet hitting.

As for the 750, it had full coverage. About the only thing that was not damaged was the seat, until they dragged it on to the roll back. If you notice how low the bike is sitting, it is on a swing arm stand. The main swingarm weld broke cleanly off.
