It's possible on a scooter, which has a lower speed, low centre of gravity (so you have more relative leverage) and small wheels (i.e. the amount of spinning mass is less, and closer to the axis of spin). On a big bike with big wheels at high speed, you can only make very gentle adjustments in the lean angle.
