Front SuspensionGeneralThrough the optimal location of components, and the use of Nachlauf geometry, the front suspensionprovides excellent riding comfort and controllability.Nachlauf GeometryThe front suspension uses the Nachlaufgeometry in which the king pin axis is locatedahead of the axle center. As a result, excellentstraight-line stability and steering feel has beenimproved.

Through use of the multi-leaf type linear control valve, changes in the damping forceare made constant at low piston speeds, thus realizing excellent riding comfort and controllability.

Consequently, only the function of thecoil spring is applied when the suspension stroke is small during normal driving, in order to realize a softand comfortable ride. However, when the inner wheel makes large rebounds, such as when the vehicleis cornering, the functions of both the rebound spring and the coil spring are combined in order to reducethe elongation of the entire suspension. As a result, the vehicle has excellent maneuverability andstability."

Theillustration shown below indicates the lateral force distribution on suspension arms of the right side rearwheel during left cornering. This causes the wheels to toe-in, in order to ensure the proper stability of therear suspension.Braking GeometryWhen the longitudinal force is generated, the displacement locus of the No. 1 and No. 2 suspension armswill toe-in as shown below, in order to ensure the stability of the vehicle. .
