Good article. I think it's interesting that there was nothing mentioned about the gyroscopic effect and power of a bike's moving wheels in relation to countersteering. As scooter riders we're also in a good place to prove its benefits over peg steering/tank pressing as we have neither. With the free space of our running boards and no pegs we have noting to press against.
Years ago I watched a video where someone welded the front wheel of a MC so it couldn't turn. The idea was to show how far the bike had to travel to make a 180 degree turn using just leaning, peg or tank pressure. Riding in a open area it took a rider hundred of yards just to turn the bike around. When using another bike (with a free moving front whee;) and employing counter steering it took only a matter of meters.
Anyway, this video may help too,
