Why do we have to lean the motorcycle while turning?

1. Correct answer: To lesser the effect of the centrifugal force (a force acting on the motorcycle whilst turning).
2. To improve tire grip on a dry or wet roadway.
3. To completely annul the effect of the centrifugal force.
4. To improve our field of vision and our ability to respond to surprises on the road.

WhyLeaning the motorcycle reduces the effect of centrifugal force. It cannot remove it completely.
