The last time I researched this I found that statically 30% of impacts happen to the facial area and 30% happen in the area around your ears and nape. I doubt that any of us are so pretty we can afford to have our face peeled off in a slide.
My suggestion is to find a full helmet that fits properly and is comfortable. Then wear it.
Thanks for the information Vince.
That statistic alone makes a strong enough argument towards the full face.
My guess is that the older and more wiser riders are bigger on safety.( Whereas the muscle heads are more into the sub culture which includes sleeveless shirts...and beanie helmets.)
Getting a safe and comfortable fitting helmet is important to me. And just yesterday, when a local rider suggested that a full face was the way to go, I decided to pay quick heed to his advise ...even if I'm only riding on the back roads.
He took a spill at 30 mph and wound up rubbing the face portion of his helmet on the asphalt. If it weren't for the FF, it could have been ugly.
I enjoy the feel of the 3/4...but I like my face too!
Time to do some shopping.
