DESCRIPTION

The suspension is double wishbone type at the rear. Optimal suspension geometry and wheel alignment
are achieved through analysis of the component design, materials and characteristics to provide a high
level of controllability and riding comfort.
The support rigidity of the suspension has been realized through the adoption of the rear subframe.
