I am with Kevin on this one...........
For several reasons.
First, Steering a motorcycle wheelieing is accomplished by leaning.
Second, drag racers with big tire bikes basically heard them one direction or
the other by hanging off to the side they would like to be heading. Maybe
this is repititious of the first scenario since their front wheels are not on
the ground.
The third case is somewhat similar to the first in that while I was riding a
R-1 under HARD acceleration, I input body english to keep it headed where I
wanted.
I have no idea what the BS bike is..... but my experience indicates there is
more to this than meets the eye.
