Problems solved by technology

[0006] However, since the fuel tank T is arranged away from the engine Eu, when the fuel tank T has a fuel pump, it is necessary to lengthen the fuel piping.
In particular, since the fuel pump is high-pressure, the fuel piping needs to be a pressure-resistant hose, which is expensive
That is, in the prior art, there is room for improvement in terms of cost

Abstract

The invention aims at providing a configuration of a flexible tumbrel which can shorten a fuel tubing as well as ensure the convenience for passengers to across get on or get off. A fuel tank (26) is arranged at the front part of a single beam type frame (12) adjacent to a jointing pipe (11). An air filter (27) is arranged at the bottom of the fuel tank (26) and the front top of an engine. An inspiration system (28) (in the figure 3 consisting of a connecting pipe (28a), an air damper body (28b) and an intake manifold (28c) is extended to the back bottom of the air filter (27). The bottom of the single beam type frame (12) hangs a cylinder (29) and an engine extended to the forward horizontally. The inspiration system (28) is connected with the cylinder (29). The fuel tank is arranged at the single beam type frame near the horizontal cylinder. Namely, the fuel tank is arranged at the top of the cylinder, thereby shortening the fuel tubing.

Description

technical field [0001] The present invention relates to the arrangement of a fuel tank of a motorcycle. Background technique [0002] Small (small displacement) motorcycles having a single-beam frame consisting of a frame extending rearward and downward from a head pipe and an engine whose cylinders are arranged approximately horizontally have been used in various applications (for example, Refer to Patent Document 1). [0003] Patent Document 1: (Japanese) Unexamined Patent Publication No. 2004-299627, FIG. 1 [0004] In FIG. 1 of Patent Document 1, Ft is a single-beam frame (Monobac frame) composed of a single frame extending rearward and downward from the head pipe, Eu is an engine whose cylinders are arranged in a substantially horizontal direction, and S is the seat and T is the fuel tank. [0005] By setting the air cylinder approximately horizontally, the body cover in front of the seat S can be lowered so that the foot can pass through the "valley" portion created...
