Abstract: An exhaust device for a multi-cylinder engine for connecting both exhaust passage members with a communicating hole formed in each one when the two exhaust passage members are to be spaced apart. A base plate has a through hole communicating with the communicating hole and a cover plate for covering the outside of the base plate. The outer circumferential area of the through hole of the base plate overlaps the outer surface of the exhaust pipe with the entire outer circumferential area of the through hole is welded to the exhaust pipe. The edge portions on both sides of the cover plate are welded to the base plate so as to surround the outer side of the through hole. The area extending between edge portions on both sides of the cover plate is welded to the front and rear edge portions of the base plate.

Abstract: An ABS modulator for a front wheel is supported on the side surface of an inclined portion located forward of a portion, having the largest width, of the right main pipe with a unit supporting stay in between, while being arranged in a space inside the front cowl covering the front side of the inclined portion. The ABS modulator is arranged on the outer side of the main pipe. Accordingly, it is possible to avoid a case where the arrangement space for other components is occupied by arranging the ABS modulator in a space on the inner side of the right and left main pipes, and to support the ABS modulator by utilizing the main pipes having a high rigidity. Further, the resulting configuration allows to ABS modulator to be located in a portion having a high rigidity without occupying a space for other components, such as an induction system.

Abstract: A parking brake operating lever is arranged to allow a rider to operate the operating lever without leaning forward to a large extent, while securely avoiding an inadvertent operation. An operating mechanism for a parking brake is provided to a position, covered with a front cowl, of a right-side main pipe, below a tank cover. The operating lever is positioned to be partly exposed from a lower end portion of the side surface of the front cowl. Since the operating lever is positioned in a vicinity of the front end portion of a seat, the operating lever is easy to operate. Concurrently, since the most part of the operating lever is covered with the front cowl, an inadvertent operation is avoided.
