Abstract: A vehicle front structure including: a heat exchanger placed upright in a vehicle front part; a left air guide plate formed upright on a left side of the heat exchanger to extend frontward therefrom; a right air guide plate formed upright on a right side of the heat exchanger to extend frontward therefrom; a drain opening formed at a bottom of only one of the left and right air guide plates; and an air intake port for an engine formed above the heat exchanger, and arranged closer to the one of the left and right air guide plates in which the drain opening is formed, from a center of the heat exchanger in a left-right direction.

Abstract: An engine room harness routing structure is provided that allows a harness trunk line to be routed without imposing restrictions on the design of the vehicle body. The harness trunk line is housed in an upper position inside a cowl box having a relatively large amount of leeway in its cross sectional area and is routed in the widthwise direction of the vehicle inside the cowl box. Consequently, there is no need to secure space for mounting the harness between the under surface of the cowl box and the upper surface a brake master cylinder back installed there below. As a result, the problem of the height of the cowl box from the ground increasing and affecting the design of the vehicle body can be avoided and the layout of harness trunk line can be established so as not to restrict the vehicle model.

Abstract: A radiator device for a motorcycle operatively connected to an engine unit provided with a water jacket and in which cooling liquid circulates comprises a pair of first and second radiator units arranged bilaterally in upright fashion with respect to the motorcycle body. Each of the radiator units is composed of upper and lower tanks in an upright arrangement thereof, the upper tank of the first radiator unit having a top portion disposed at a level lower than a top portion of the upper tank of the second radiator unit. The cooling water directly introduced into the upper tank of the first radiator unit is then divided and one branch flow of the cooling water is fed into the upper tank of the second radiator unit through means of another water tube interconnecting the upper tanks of the first and second radiator units.
