You are a practical rider, just try it.

Even if you haven't figured it out it may be entertaining to hear some different theories.
That is something that anyone can find experimentally:
1) From total stop, balance the bike vertically, put both feet up on the pegs.
From that position, if you don't turn the handlebar, the bike will fall to either side.
Repeat and verify: the bike has no preferred side to fall onto.
2) From total stop, balance the bike vertically, put both feet up on the pegs.
From that position, turn handlebar all the way to the left (full lock), the bike will consistently fall to the left side.
Why?: You have moved the CG of the bike left and is now off the line that joins the contact patches of the front and rear tires.
That is steering for you, and will work for standing still and for low speeds.
