A motorcycle frame is made of steel pipes or light alloy pipes that are cut and bent into a desired length and then welded and joined together. The steering shaft of the front fork is attached to the head pipe at the front end of the frame, so if it is not rigid enough, it will affect steering stability. For this reason, the structure is such that the front left and right tubes are welded to the upper part of the head pipe, the left and right lower tubes are welded to the lower part, and a reinforcing plate is provided. If the front left and right tubes are positioned high in this way, the rear upper left and right tubes, which are welded to the front left and right tubes, will also be positioned high, which raises the position of the rider's seat and raises the inconvenience of raising the center of gravity while riding. .

In view of this, the object of this invention is to provide a motorcycle frame that allows the height of the seat to be lowered while providing high rigidity in the vicinity of the head pipe.
以下、本考案を図面に示す実施例について説明

る。 The front left and right tubes 1 are provided in pairs on the left and right, and their front ends are abutted against the lower part of the head pipe 2 and welded. Then, the rear portion is lowered obliquely downward, and the rear end is abutted against the upper position of the pivot 5 at the front end of the rear fork 4 at the rear of the left and right lower tubes 3 and welded. The front portions of the pair of left and right lower tubes 3 are welded to a bridge piece 6 that connects the front portions of the front left and right tubes 1, and the front ends are abutted against and welded to the head pipe 2. T-shaped front upper tube 7
The front end is welded against the upper part of the head pipe 2, and the left and right rear ends are welded to the middle of the front left and right tubes 1. The pair of rear upper left and right tubes 8 have their front ends located in front of the rear ends of the front upper tube 7 and the front left and right tubes 1.
At the same time, it is welded to the rear ends of the left and right lower tubes 3. The rear portions of the rear upper left and right tubes 8 are connected to the left and right lower tubes 3 by left and right rear lower pipes 9 and 10. 11 is a fuel tank, and 12 is a seat.
しかして、前左右チユーブ１は、ヘツドパイプ
２の下部から斜め下に伸びて左右下チユーブ３の
後部に溶着されていて、位置が低い。この低い位

低くできる。前左右チユーブ１と左右下チユーブ
３の前部は交錯しており、前上チユーブ７と後上
左右チユーブ８の前部も交錯しているので、ヘツ
ドパイプ２付近の剛性も高くできて、良好な操縦
安定性が得られる。 The front left and right tubes 1 extend diagonally downward from the lower part of the head pipe 2 and are welded to the rear portions of the left and right lower tubes 3, and are located at a low position. Since the front ends of the rear upper left and right tubes 8 are welded to the lower front left and right tubes 1, the rear upper left and right tubes 8 can also be lowered, and the seat 12 mounted thereon can also be lowered. The front parts of the front left and right tubes 1 and the left and right lower tubes 3 intersect, and the front parts of the front upper tube 7 and the rear upper left and right tubes 8 also intersect, so the rigidity near the head pipe 2 can be increased, resulting in a good design. Maneuvering stability is obtained.

As explained above, this idea involves welding the front ends of the front left and right tubes to the lower part of the head pipe, and welding the rear ends to the upper side of the rear hawk pivot at the rear of the left and right lower tubes. At the same time, weld the front end to the upper part of the head pipe, weld the front end of the T-shaped front upper tube to the upper part of the head pipe, weld the left and right rear ends to the middle of the front left and right tubes, and weld the front end to the upper part of the head pipe. Since the front end of the seat is welded to the front left and right tubes in front of the rear end of the front upper tube, the positions of the front left and right tubes and the rear upper left and right tubes are low, making it possible to lower the height of the seat. Therefore, the center of gravity is low and stable driving is possible. In addition, the front parts of the front left and right tubes intersect with the front parts of the left and right lower tubes, and the front parts of the front upper tube and the rear upper left and right tubes also intersect, which increases the rigidity near the head pipes and improves steering stability. .
