The invention discloses a shock-absorbing pedal of a motorcycle. In the shock-absorbing pedal, a rear connecting tube consists of an upper connecting tube and a lower connecting tube, wherein, the rear part of the lower connecting tube turns up to form an inclined section, and the lower end of the upper connecting tube is sheathed into the inclined section; a first spring is arranged in the inclined section of the lower connecting tube, the lower end of the first spring is abutted with a first locating plate fixed in the inclined section, and the upper end of the first spring is abutted with a second locating plate on the bottom end of the upper connecting tube; and a second spring is sheathed on the upper connecting tube, the lower end of the second spring is abutted with the second locating plate, and the upper end of the second spring is abutted with an inner flange at an upper port of the inclined section of the lower connecting tube. In the invention, shock of the foot pedal is lowered during the running process of the motorcycle by virtue of elasticity of the springs, which effectively improves riding comfortability; and the shock-absorbing pedal has the characteristics of artful design, simple structure, easy reconstruction, low reconstruction cost and the like, and can be widely applied to various two-wheeled motorcycles.
