The lean angle of the motorcycle is determined by the balance of forces and torques necessary to accelerate through the turn:
where
is the angle with respect to the vertical, v is the speed, R is the radius of the turn, and g is the acceleration due to gravity. (Note:
certain factors, such as the angular momentum of the
motorcycle's rotating parts, have been neglected in deriving this simple
formula.)
