While making normal turns, what must the bike and rider do?

Leaning together at the same angle is crucial for achieving balance and stability during a turn. When a motorcycle makes a turn, both the rider and the bike must lean into the curve to counteract the forces acting on them, particularly centrifugal force. Leaning together allows the rider to maintain control and helps to prevent the motorcycle from tipping over.

If the rider does not lean with the bike, it can lead to a loss of balance or traction, making it difficult to execute a smooth and safe turn. Therefore, coordinating the lean between the bike and the rider is essential for successful navigation in curves and maintaining control throughout the maneuver.
