At the risk of thread drift, I would comment in regard to front/rear brake usage.
There's a large group of motorcyclists that won't use the front brake at all. They've heard some baloney about using the front brake, like going over the bars, unexpected locking of the front wheel and other tales. They instinctively use only the rear brake and suffer the consequences. You can hear it in some of the stories you hear, the classic line being "I had to lay it down". Yep, too much back brake will often times result in a slide which leads to the mistaken impression of one's controlled, active participation in "laying it down".
A very long time ago when I was learning the fine points of dirt riding/motocross racing I would practice riding on dirt with the front wheel locked. It can be done and it gives you a sense of what to do when the front locks unexpectedly in a race situation.
Learning proper use of both brakes is crucial to stopping effectively and may save one's life at some point.
