What complicates an emergency stop while in a curve?

An emergency stop while in a curve is complicated primarily because traction is already being utilized for cornering. When a rider is in a curve, the tires must maintain enough grip to keep the motorcycle upright and on the intended path. This means that a significant portion of the available traction is committed to the task of turning rather than stopping.

When an emergency stop is required, the rider needs to apply the brakes effectively to reduce speed or come to a halt. However, if too much braking force is applied while leaned over in a turn, it can lead to a loss of grip and potentially cause the motorcycle to skid or crash. This delicate balance of maintaining control while attempting to stop makes the situation much more complex than if the motorcycle were upright and traveling in a straight line.

The other factors listed, such as visibility, steering adjustments, and increased speed, can play roles in complicating a stop, but they do not directly affect the fundamental issue of traction allocation in a curve. In essence, the primary challenge is that the motorcycle's stability and control are compromised because some of the traction is already being used to negotiate the turn.
