ABSTRACT:
A cylindrical steering damper apparatus for a motorcycle has a relatively simple structure, in which a gradually increasing damping force is generated according to the turned angle when a handlebar is turned, and the damping force is not generated when the handlebar is returned. The cylindrical damper is disposed between a head pipe, for pivotally supporting a steering stem, and a fork bridge of a front fork, so as to be the shortest when the handlebarbar is at a neutral position. The cylindrical damper is connected to the head pipe and the fork bridge via spherical ball-and-socket joints. The cylindrical damper generates the damping force when being expanded. Since the cylindrical damper is expanded when the handlebar is turned in either a left or right direction, a damping force is generated.
