PURPOSE:To effectively cool the engine for a motor cycle with a simple construction by disposing a lateral radiator with its front side lowered between an engine cylinder head arranged at the lower center of a body and a tank mounted on the upper front portion of the body. CONSTITUTION:When a motor cycle runs, running wind passes through a duct 12 or the like and the recess portion of a tank 3 into a radiator 9. When the running wind passes from the upper surface toward the lower surface over the radiator 9, it cools the collant by heat exchange. This coolant is passed through a pipe 11 to be circulated into a cylinder 10 and a cylinder heat 8 to thereby cool the engine 2. Since the radiator 9 can be contained within the width of the tank 3 without any side projection, no disturbance occurs nor scratches when the motor cycle is fallen down. |
