Abstract
A rear-wheel suspension system for a two-wheeled vehicle capable of further reducing a vehicle width. An upper end of a coil spring of a shock absorber includes a tubular damper case, a rod connected to a piston disposed within the shock absorber and protrusively provided to be capable of making strokes with respect to the tubular damper case and an external hydraulic sub-tank positioned to be lower than an upper end of the shock absorber. Vehicle body component parts include a connecting tube and the sub-tank disposed to be close to the shock absorber above the coil spring.
Claims19
A rear-wheel suspension system for a two-wheeled vehicle comprising:
- a pair of right- and left-side center frames connected to a rear portion of a main frame extending rearwardly and downwardly from a head pipe;
- a swing arm having a front portion pivotally supported by the center frames and a rear portion for supporting a rear wheel;
- and
- a shock absorber, disposed wherein a longitudinal direction of the shock absorber coincides with a vertical direction, having an upper portion pivotally supported on a vehicle body side between the center frames and a lower portion pivotally supported on the swing arm side;
- wherein the shock absorber includes a tubular buffer and a spring disposed around the buffer with an upper end of the spring being positioned to be lower than an upper end of the buffer and a vehicle body component part being placed to be close to the buffer above the spring.
