ABSTRACT:
A steering damper is provided coaxially with a steering shaft, and a handlebar load is provided by causing a variable valve to generate damping force, using rotation of the steering shaft. The damping force is variably controlled in response to vehicle speed. The damping force is fixed to a minimum value C1for vehicle speeds equal to or below first reference speed V1, fixed to a maximum value C2for vehicle speeds equal to or above second reference speed V2, and variably controlled in response to vehicle speed and acceleration in an intermediate speed range. Fine maneuverability of a vehicle body is achieved by reducing a load on a handlebar at low vehicle speeds, and a stable movement of the vehicle body is maintained at high vehicle speed by increasing the load on the handlebar and thereby suppressing deflection of the handlebar.
