Camber Angle


Camber angle is the angle made by the wheel; specifically, it is the angle between the vertical axis of the wheel and the vertical axis of the vehicle when viewed from the front or rear.

For the sake of argument lets say, looking from the front of motorcycle, If the top of the wheel is further out than the bottom, it is called positive camber; if the top of the wheel is further in than the bottom, it is called negative camber.

True center hub steering has zero camber when going straight, positive camber when steered left, and negative camber when steered to the right.

For maximum straight-line acceleration and stability the greatest traction will be attained when the camber angle is zero and the tread is flat on the road.

Correct change in camber angle while cornering improves grip because a rubber tire tends to roll on itself while cornering. If the tire had zero camber, when cornering, the inside edge of the contact patch would begin to lift off of the ground, thereby reducing the contact patch.
