GENERAL DESCRIPTION
Stabilizer Bar
Center Link
Shock Absorber
Trailing LinkLateral Rod
The rear suspension is a 4-link, coil spring type
suspension with a stabilizer, consisting of two
trailing links, center link, lateral rod, shock
absorber, and stabilizer. In this suspension, the
links are specially arranged to enable the rear axle
to move freely, thereby expanding suspension
stroke, reducing friction, and improving lateral
rigidity and roll control. All these result in improved stability, riding comfort, and rough road
maneuverability.
Each link connects the axle housing with the frame
through a rubber bushing. The axle housing is
supported by the trailing links and center link
longitudinally and by the lateral rod latitudinally.
