Hmmm...I mean, some of us are fast, but this isn't F1, tire traction isn't the limiting factor to speed all that often. Having more than a half a horsepower on tap would make you a lot faster than harder braking.

That being said, learning all sorts of bike handling can be done by learning to operate at the limit of what your bike capable of. So by all means, go to to it. It's a lot of fun.
