The resulting radius can be roughly approximated (within 2% of exact value) by: :r = \frac{w\cos \left (\theta \right )}{\delta \cos \left (\phi \right )} where r is the approximate radius, w is the wheelbase, θ is the lean angle, δ is the steer angle, and φ is the caster angle of the steering axis.
In traditional bike designs, with a steering axis tilted back from the vertical, positive trail tends to steer the front wheel into the direction of a lean, independent of forward speed.
The radius of the turn of an upright (not leaning) bike can be roughly approximated, for small steering angles, by: :r = \frac{w}{\delta \cos \left (\phi \right )} where r\,\! is the approximate radius, w\,\! is the wheelbase, \delta\,\! is the steer angle, and \phi\,\! is the caster angle of the steering axis.
Shimmy vibration is the oscillatory motion of the fork wheel assembly about the steering axis.
Two representative cases are studied: the wheel runs straight forward and perpendicular to the slope, and the wheel is in a steering maneuver with an inclined steering axis.
In this paper, a model of motorcycle is considered to define the damping factors generally required on the steering axis to ensure safety and comfort in all conditions.
