of the damping ratio are characteristic of each motorcycle and often can’t be changed without upsetting the whole vehicle configuration, this article will focus on the component dependent only on the steering damper.
From now on, referring to the steering damping, it will be thus considered only the damping coefficient c of the steering damper instead of the total damping coefficient.
As shown in section 2.1, the damping coefficient c of the steering damper is fundamental to stop the steering oscillations at high speeds. So it can be used, for example, the damping coefficient of the steering damper as a DP to achieve the FR1. Unfortunately this DP, that is constant for conventional steering dampers, affects even the rider comfort, as shown in equation (3):
