A cowling structure is provided for a motorcycle in which a radiator is disposed behind a front wheel of the motorcycle. The cowling structure includes a main cowling and a sub cowling. The main cowling covers a periphery of the radiator from the front of a handlebar. The sub cowling is provided in the rear of the cowling through a space. The sub cowling is separate from the cowling. The cowling structure allows wind to effectively hit a radiator, and reduces a force necessary for inclining a vehicle body at the time of cornering.

Cowling structure for motorcycle

A motorcycle is provided having an engine disposed between a front wheel and a rear wheel and functional components, e.g., a first radiator, a fuel pump, a rear shock absorber, etc., are arranged, as viewed from the side, on a circumference of a circle with a radius R corresponding to a distance from a crankshaft, serving as a center, to a corner of an oil pan, serving as a part of the engine most distant from the crankshaft, to concentrate the functional components of the motorcycle at positions substantially equidistant from the crankshaft of the engine whereby a mass concentration toward the vehicle body center of a motorcycle is achieved.
