Nearly didn't even make it out of my own driveway! As I powered up the driveway I took one hand off the bars to wave good bye to my son, the front wheel lifted and the bike pitched massively sideways but I kept the power on and managed to hold it. When it doubt, power out!
The second vaguely related one was caused when I was braking fairly hard and a dodgy wire in my throttle shorted wide open for a split second. I guess it caused the front wheel to lift a bit and then went squirelly under brakes.
