In a motorcycle having a engine, a fuel tank provided above the engine, and a carburetor provided behind a cylinder of the engine, a stiffener plate and a wind deflector plate are provided at such a position as to cover the front side of an engine upper space defined between the top of the cylinder and the bottom of the fuel tank. The stiffener plate and the wind deflector plate are supported to a pair of right and left down frames. The wind deflector plate is secured together with horn stays for mounting horns. The wind deflector plate has louvers for deflecting and guiding an air flow to the cylinder.

A rear fender mounting structure includes features for simplifying the assembly of a rear fender, sub-frame, and grab rails to a rear frame of a motorcycle. The sub-frame has brackets welded onto it. The brackets include holes with protruding collars defining the holes. The rear fender has holes lined with rubber bushings. The protruding collars are fitted into the rubber bushings. The rear fender includes a bracket which is hooked over a crossbar of the motorcycle frame. The fender is then lifted from its rear end, by pivoting the bracket about the crossbar. When alignment occurs between the bracket holes and holes in the rear frame, linkage plates with bolts extending therefrom, are employed. The bolts are passed through the aligned holes. Next, holes in the grab rails can be easily aligned with the ends of the bolts. Nuts are used to secure the arrangement. The backrest mounting structure includes features for dampening vibrations in the backrest, and for improving the appearance of the motorcycle by placing the attachment of the backrest inside the grab rails. Upper and lower rubber members sandwich lower portions of the backrest supporting members. The lower portions of the backrest supporting members are tilted 45 degrees relative to horizontal and are located inside the grab rails.
