Motorcycles are inherently stable. It's the riders who make them go down most of the time. (Does this sound like Keith Code? It should.)
I remember the first time I did a two-wheel drift on a street bike. I was going through a corner on Highway 16 between Medina and Kerrvile, Texas. I had the bike leaned over farther than I ever had in that corner, and as I rolled on the throttle I felt both tires start sliding. Before I could react (betchya never knew slow reflexes could be an asset) the tires gained traction and I was set up perfectly for the next corner. It was a lot of fun, but I was always a bit slower in that corner.
The lesson I learned is to trust the bike and not do anything to upset it in a corner. When it doubt, gas it and go.
