Development of Electronically Controlled Hydraulic Steering Damper for Motorcycles

Article of Honda R&D Technical Review Vol.16 No.1


The world’s first electronically controlled hydraulic steering damper for motorcycles, HESD (Honda Electronic Steering Damper), has been developed. That always gives optimum damping characteristics during running. Handling characteristics and “Kickback” phenomenon was analyzed using a motorcycle with or without a steering damper. The steering damper with optimum damping characteristics according to the speed and acceleration of vehicle is needed to reduce “Kickback” phenomenon. An electronically controlled linear solenoid is applied to alter flow resistance of the damper. The HESD reduced kickbacks maintaining sporty handling at the low speed running.
