    • PURPOSE: To reduce the number of parts and to get rid of the strength affective defects, by forming the front part of the frame to one body and by connecting the rear part of the frame which is formed from a plate, and a vertical pipe.
      CONSTITUTION: The front part of the frame is bulge-formed to have a T-shaped head part 4 at its tip. At the front and rear of it there is located a hole for fitting the bearing of the front fork. Near the square section at the end of the central pipe 5 is formed a hanger 6, and a hanger pipe 7 is inserted in the hole located at the hanger 6.
