So then the question is, if you counter precession with a mass rotating in the opposite direction and approach zero does that mean the motorcycle is now going to steer like a car at speed?

That's the whole point, Matt. A normal wheel including brake disc
always has precession, which is the "gyroscopic effect" you are
talking about. You can counter precession by a rotation in the
opposite direction.
