<p>The utility model provides the rear-wheel suspension structure of a motorized two wheeler, which aims to improve the driving feel, inhibiting the large-scale reduction of the torsional rigidity relative to a rear rocker arm, and regulating the rigidity of the entire motorized two wheeler along the width direction thereof. The rear rocker arm (5) comprises a pair of arm parts (20, 20) arranged left and right, a crossbeam (21) erected between the left arm pat and the right arm part, and a pair of gusset plates (22, 22) arranged left and right and configured to connect the rear side of the crossbeam with the inner sides of the arm parts (20, 20). Each gusset plate (22) is provided with an upper plate part (40) and a sagging part (41) configured to extend downwards from edge part of the upper plate part (40), wherein the sagging part (41) is provided with a notch part (42) and the lower end of the notch part (42) is cut off towards the edge part of the upper plate part (40). According to the technical scheme of the utility model, the large-scale reduction of the torsional rigidity is inhibited, and the rigidity of the entire motorized two wheeler along the width direction thereof is lowered.</p> |
