Stopping quickly in a curve requires the rider to _____.

Stopping quickly in a curve necessitates that the rider progressively applies both brakes until the motorcycle is upright. This method is crucial because braking while leaning can destabilize the motorcycle, potentially leading to loss of traction and control. When a rider leans into a curve, the forces acting on the motorcycle are balanced between gravity and centrifugal force. If the rider were to apply the brakes suddenly while still leaned over, it could result in a skid or a wipeout due to the shift in weight distribution and reduction of tire grip.

By progressively applying both brakes and ensuring the bike is as upright as possible when coming to a stop, the rider maintains better control and stability. This technique helps in transferring weight back onto the tires, enhancing friction and grip, which are essential for effective braking. It allows the rider to stop safely without losing control of the motorcycle in a challenging situation.
