Abstract

A body frame for a motorcycle for ensuring the binding rigidity between an engine and a body frame while reducing the weight of the body frame, and also increasing the flexibility of the disposition of motorcycle components. A body frame includes a first frame member and a second frame member, the first frame member and the second frame member being separated relative to each other. At least one engine support is formed integrally with the first frame member. Another engine support and a pivot portion for a rear swing arm is integrally formed with the second frame member. The first frame member gradually expands towards the at least one engine support with three approximately M-shaped projections being formed at an end of the first frame member wherein the at least one engine support is formed at these projections.

Description

technical field [0001] The invention relates to an improvement of a motorcycle frame. Background technique [0002] The main form of the motorcycle frame is that the left and right main frames are integrally arranged on the head pipe, and the engine is suspended and supported on the main frames. [0003] In addition, there is also a structure in which a part of the left and right main frames can be separated, and the engine is suspended and supported on the main frames. [0004] A well-known vehicle frame is a structure in which a main frame for suspending and supporting an engine and the like is made into a separate structure (for example, refer to Patent Document 1). [0005] [Patent Document 1] Japanese Patent Application Laid-Open No. 2004-256005 ( figure 2 ) [0006] In Patent Document 1 figure 2 Among them, the frame of the motorcycle is divided into a front frame 5 and a rear frame 20 for configuration, the front frame 5 is installed on the cylinder block 8, and t...
