The saddle binding position adjustment and the saddle
folding position adjustment can be executed in the system
setting menu. However, the adjustments in the system set-
ting are based on the adjustment value of this simulation.
If, therefore, the adjustment value of this simulation is set
to an extreme level, the adjustment range in the system
