I would say a large % of safety on a motorbike is down to you, not just gear but forward vision, reading the road and more importantly - reading others.
This really, a lot of it is down to yourself and the choices you make. Here's a few examples
I've been riding 5.5 years (since 16) and I've crashed twice, both on my 125 I went too fast in sketchy conditions locked the front and slid down the road. Both my own fault due to inexperience.
My Dad who's been riding longer than I've been around has crashed 3 times since I started. 2 times were his kinda own fault, he hit a gravel patch while braking to a roundabout and dropped it at low speed. Second time he went into the back of a car at a junction and just bumped it. The third accident was nothing to do with him, he was riding along at the speed limit and a taxi pulled out in front of him and he went over the bonnet and just suffered bruising too the ribs more than anything.
My friend who has been riding 3 years had one crash that nearly cost him his life. Went into a corner and lost the front, we were doing a good 80mph getting our knees down but he went a step further and ended up hitting the central reservation at that speed. 4 broken ribs, 3 broken vertebrae, broken leg and a lacerated liver later and he managed to just pull through. Again, no one to blame but himself.
Moral of the story, there will always be factors you can't control but for the most part it's down to yourself. It's not like you're signing your life away by wanting to ride a bike, it depends entirely how much you trust yourself more than anything.
Like anything in life there will be factors you can't control, but you don't refuse to cross the road because you MAY get hit do you? The statistics may not be in the favor of bikers but there's a lot beneath the surface of them that they don't tell you
