PURPOSE: To improve the layout of an exhaust muffler and reduce the flow resistance of cooling water and weight by forming a cooling water passage, extended outside from a water pump so as to be connected to a radiator, linearly with the shortest distance without interfering with the exhaust muffler. CONSTITUTION: A water pump is disposed at a front part in a crankcase and at a center part in a vehicle width direction, and a cooling water passage 41 led outside from the water pump so as to be connected to a radiator 13L is extended to the body side face on the side where an exhaust muffler 11 is not disposed. |
