A saddle type vehicle wherein restrictions in the weight and the layout are reduced for slimmer and lighter vehicle. Pivot plates are provided as separate bodies from seat rails. An upper end of a shock absorber is received by a cross member located between left and right seat rails. The cross member is a separate body from the seat rails. Both ends of the cross member are supported by recesses provided in the left and right seat rails at inner sides of the seat rails so as to face each other. The cross member is fastened to the seat rails by cross member fastening members. The seat rail is attached to a main frame at its one front-side end and to the pivot plate at its other front-side end. The main frame and the seat rail are fastened to each other in the vertical direction by a first fastening member.

Saddle type vehicle

A saddle type vehicle to improve the workability in fastening a frame and an engine together and thereby to enhance productivity. The saddle type vehicle includes a head pipe, a main frame extending rearwardly from the head pipe, and a seat rail located rearwardly of the main frame for supporting a seat. The main frame is fastened to the engine by fastening members being directed from an outer side toward an inner side in the vehicle widthwise direction. A knock pin is provided between the main frame and the engine, in a position in the vicinity of at least one of the fastening members.

A structure for sufficiently spacing a steering handle from a top bridge, thereby greatly improving design flexibility. A relief portion for allowing the deformation of a washer is formed to overlap a second contact surface and adjacent to a first contact surface as viewed in the axial direction of each bolt member. The first contact surface is located so as not to overlap the second contact surface as viewed in the axial direction of each bolt member. Therefore, a bending force acts on the washer to allow the deformation of the washer. That is, the washer can exhibit a spring function to relax the effect of the bending force. As a result, the steering handle can be sufficiently spaced from the top bridge to thereby greatly improve design flexibility.

Fastening device

In a motorcycle, a head pipe is provided with one main frame part that extends rearwardly from the head pipe and a rear frame that extends substantially downwardly from the rear of the main frame part. A pivot is pierced in a pivot support part provided to the rear frame with a swing arm being attached to the pivot so that the swing arm can be vertically swung and a rear shock absorber unit is positioned between the swing arm and the side of the body frame. The main frame is cast in an aluminum alloy and the rear frame on the upside and the downside of the pivot supporting part projects on both sides of a vehicle from the pivot supporting part to attach right and left brackets for supporting both ends of the pivot.

Body frame of motorcycle

A motorcycle body frame includes a main frame including a head pipe for supporting a front suspension at the front end thereof, a single leading frame portion extending rearwardly from the head pipe, and a rear frame portion for supporting a rear wheel suspension. The rear frame portion extends substantially downwardly from a rear part of the leading frame portion. The main frame, cast from an aluminum alloy, includes two component parts arranged front-to-rear. For example, a front frame portion is provided, and a rear frame portion is fixed to the rear side of the front frame portion. The leading frame portion has a small section portion, where the main frame is smallest in sectional area, disposed substantially centrally in the longitudinal direction thereof. The two component parts of the frame are joined at a coupling portion of the main frame situated in back of the small section portion.

Frame assembly for a motorcycle

In an exhaust system for a motorcycle in which an engine main body of a multi-cylinder engine has an oil pan on a lower portion thereof, and is mounted on a vehicle body with a plurality of expansion chambers being connected to a downstream side of an assembled portion of a plurality of exhaust pipes that extend out of the respective cylinders of the engine main body, respectively. The muffler includes a first expansion chamber that is connected to the assembled portion and the other expansion chambers that are the assembled portion are disposed on one side of the oil pan. The first continuous to the first expansion chamber. The respective exhaust pipes and expansion chamber is disposed on the other side of the oil pan with the other expansion chambers being disposed to the rear of the engine main body.

Exhaust system for motorcycle

A space is secured inside left and right pivot plates and a space is secured in front of a rear wheel to increase flexibility in design. In a motorcycle including left and right pivot plates provided at the rear portion of main pipes, a swing arm is provided on pivots so as to be capable of moving in the vertical direction. Only one rear suspension is interposed between the swing arm and the main pipe that is disposed outside the pivot plate in the direction of the width of the vehicle. A lower end of the rear suspension is connected to an upper surface of an arm portion of the swing arm. The rear suspension is mounted to one of the main pipe so as to extend continuously from the main pipe and substantially linearly in the direction of the length of the vehicle in a top view.

Motorcycle

A structure for mounting a front fender that can enhance rigidity of a fin without unduly increasing the thickness of the fin or decreasing the slope of the fin. In one example structure for mounting a front fender, a fin of a front fender is mounted on a fin mounting portion formed in a front fork with a bolt, and a holding member is fastened to the fin mounting portion, together with the finwith the bolt. A tip portion of the holding member is extended to a position separate from the fin mounting portion to support the reverse surface of the fin.
