1. You're added _twice_ the amount of task for stopping you now need to manage 2 separate brakes systems and tire level tractions.
2. The majority of the bike's stability is coming from the gyro of the running engine and the spinning wheels. If you lock the front and the engine is still spinning and the rear tire is still turning you have a very good chance of reducing pressure and riding out of it because the bike is still stable and tracking straight.

You lock the rear which is very easy to do while hard on the front and kill the engine you've lost much of your stability and your ability to re-accelerate and if you then lock the front on top of that the bike is completely unstable. To avoid killing the engine you now need to manage a 3rd control.

The nature of an emergency is that you aren't planning for it. It's hard to properly modulate 7 controls (front brake, rear brake, clutch, steering, body position, throttle) during a full on stop when doing planned full on stop, like on a race track.

It's going to be damn near impossible to pull it off when you didn't except it, because face it. If you where in a position to do it all right you'd not be in an emergency stop because you'd have seen it coming and already taken action to avoid the situation.
I've never heard of this notion that the engines gyroscopic forces keeps the bike upright. apparently neither has my drz.

seriously through, do a couple of panic brake practices engine-off and see there is no difference. well, unless you have a 55lb flywheel on an R6, pegged at the redline.
Yes, Android AND iphone GPS works without cellular data. Use offline maps and enjoy. (thanks drtbyk!)
