The invention discloses an upper fork structure of a shock-absorbing front wheel fork and a processing method of the upper fork structure. The upper fork structure comprises a vertical pipe, a U-shaped pipe and two shoulder cover piece assemblies, wherein the U-shaped pipe is formed by bending a single pipe; the top part of the U-shaped pipe is welded with the bottom part of the vertical pipe; the two shoulder cover piece assemblies are installed on the outer side of the top part of the U-shaped pipe; the two shoulder cover piece assemblies are mutually connected, and also cover the welding joint between the vertical pipe and the U-shaped pipe. The upper fork structure provided by the invention is not only higher in strength and good in safety performance, but also is smooth in appearance and attractive in model; the processing method of the upper fork structure mainly comprises the processes of pipe bending, hole drilling or hole milling, vertical pipe welding, shoulder cover assembling and the like; the flow is simpler; meanwhile, the costs of raw materials, process and manpower are also lowered greatly.
