Abstract

A main frame (22) of the body frame (2) includes a forward and backward extension (221) that extends rearward from a head pipe (21), and an up and down extension (222) that extends downward from the rear end of the forward and backward extension (221). The engine (3) is attached to the up and down extension (222) and a down frame (23), but not to the forward and backward extension (221). A connecting member (24) of the body frame (2) includes a main frame coupling portion (241) and a down frame coupling portion (242). The main frame coupling portion (241) is coupled to the forward and backward extension (221), and its lower end is located lower than the upper end of the engine (3). The down frame coupling portion (242) is coupled to the down frame (23), and its rear end is located to the rear of a straight line that is parallel to a steering axis and passes through the lower end of the down frame coupling portion (241) in a vehicle side view.

Description

technical field [0001] The present invention relates to a saddle type vehicle, and more specifically, to a vehicle including a vehicle body frame and a single-cylinder engine supported by the vehicle body frame. Background technique [0002] Conventionally, a saddle type vehicle including a vehicle body frame and an engine supported by the vehicle body frame is known. As a body frame of such a vehicle, there is a body frame having a structure in which a main frame and a down frame extend from a head pipe. The main frame generally includes a front-rear extension extending rearward from the head pipe, and a vertical extension extending downward from the rear end of the front-rear extension and arranged behind the engine. [0003] For example, Japanese Patent Application Laid-Open No. 2009-214625 discloses a saddle type vehicle including a body frame having a main frame including front-rear extensions and up-and-down extensions, and a down frame. In this vehicle, the engine i...
