Abstract

This invention provides a radiator disposing structure of motor scooter type vehicle located in a place such that it can catch a wind easily and occupy a large area, and further, capable of shortening the length of the piping between the engine and the radiator. A scooter type vehicle comprises low deck type footrests 3 between a handle 1 and a seat 2, and a water-cooled engine 4 at the bottom of a body. An engine-cooling radiator 42 with large lateral width is located downwardly of the footrest surface of said footrest.

Description

technical field [0001] The invention relates to the distribution structure of radiators in small motorcycles with water-cooled engines. Background technique [0002] In conventional small motorcycles, a so-called integral swing engine, in which an engine and a transmission supporting a rear wheel are integrally formed at a rear end, is provided on a vehicle body frame as a skeleton so as to be freely swingable in the vertical direction at the lower part of the vehicle body. [0003] Yet, there is such problem in this structure: under the situation that engine is water-cooled, how to arrange radiator, that is to say, hope that radiator is arranged on the position that can easily receive wind, and can increase its area; When the radiator is arranged on the front side of the head pipe, the piping between the engine and the radiator will be long. Contents of the invention [0004] Therefore, an object of the present invention is to provide a distribution structure of a radiat...
