Shock absorber adjustment on motorcycles is critical for ride comfort, road holding, and safety. Correctly
adjusted shock absorbers ensure that the motorcycle adapts optimally to the road conditions and make it easier
for the rider to maintain control. Shock absorbers absorb the energy produced by the springs and the impacts
they receive from the road and convert it into heat energy, which is transferred to the atmosphere and partly to
the chassis. In addition to the flow rate of the oil passing through holes of varying sizes, the thickness of the oil
also determines the movement speed of the shock absorber. The springs work in conjunction with the oil, and
their stiffness is sensitive to the load and the location of the shocks. Damping adjustment is made via holes or
valves and is sensitive to speed. A motorcycle with an incorrect shock absorber adjustment can be ridden, but if
the spring stiffness is not appropriate for the rider’s weight, riding will be impossible. In this study, a reservoir
shock absorber was subjected to a dynamic test with different spring stiffness settings and CST (Kinematic viscosity,
Centistokes mm2/s) values of silicone oils. During the experiments, different weights were dropped onto
the shock absorber from variable heights to simulate different dynamic driving conditions. Thus, the amounts
and durations of shock absorber sag and springback were examined. With the artificial intelligence-based control
block developed in the Simulink environment, different driving modes can be adjusted automatically or
manually according to variable road conditions.
