Abstract

Motorcycle body frame structure. A single cradle type body frame includes: a main tube 41 extending rearwardly from a front tube 3; a central tube 42 extending downward from a rear portion of the main tube; a down tube 43 extending downward from the front tube; and a bottom tube 44 extending rearwardly from a bottom portion of the down tube, a rear portion of the bottom tube 44 being connected to a bottom portion of the center tube; where only the front tube, the main tube and the down tube are connected to each other with a reinforcing element 45, 46 and 47; the central tube is a square tube with a large lateral width and constant cross section; and a swing arm is mounted only on the square center tube. Since the front portion of the body frame has a rigid structure and the central tube has a flexible structure, the amplitude of the vibration transmitted to the front portion of the body frame is vastly different from the amplitude of the vibration transmitted to the rear portion of the frame bodywork through swing arm. As a result, the body frame does not resonate, and therefore driving comfort is further improved. (Machine-translation by Google Translate, not legally binding)
