Abstract: An operation pedal system that is installed in a straddle-type vehicle includes an operation pedal having an arm portion and a pedal portion, and a tread surface forming member that is attached to the pedal portion to form a first tread surface above the pedal portion that receives a stepping force when a stepping operation is performed on the operation pedal. In the operation pedal system, the tread surface forming member is separate from the operation pedal, and the tread surface forming member has a body portion having a tread surface forming surface forming the first tread surface on an upper surface, and an attachment mechanism provided on the body portion for detachably attaching the tread surface forming member to the pedal portion.

Abstract: A spoke wheel for a straddle-type vehicle includes a rim having an outer peripheral surface on which a tire is mounted and an annular shape, a hub supported by an axle on an inner side of the rim and having a tubular shape, and a plurality of wire spokes connecting the rim to the hub. The rim is formed with a plurality of spoke holes through which the plurality of wire spokes pass and support surfaces receiving head portions of the plurality of wire spokes on one end sides of the plurality of spoke holes. Each of the support surfaces has a groove shape extending in a wheel rotation direction.

Abstract: There is provided a sensor support structure. A bracket is fixed to a vehicle body frame comprised of a plurality of frame members. A sensor is attached to a first attachment surface of the bracket. A component is attached to a second attachment surface of the bracket. The sensor is disposed in a space surrounded by the plurality of frame members of the vehicle body frame.

Abstract: There is provided a swing arm configured to be coupled to a vehicle body frame to be vertically swingable via a pivot shaft. A main body has a pivot pipe in which the pivot shaft is to be inserted. A pair of right and left arm parts extend rearward from the main body. The main body is made by casting to have a hollow structure. The main body is provided with a rib configured to vertically partition an internal space thereof. The rib is connected to the pivot pipe at a place spaced from a connection place between the pivot pipe and an outer wall part defining an outer surface shape of the main body.

Abstract: A rear rear-fender bracket integrally coupled to an upper portion and a lower portion of a rear rear-fender that is mounted to a rear portion of a vehicle body of a motorcycle, extending rearward and downward, and covering a rear wheel from upward and rearward, is provided to the rear rear-fender, and forms, with an internal surface of the rear rear-fender, a closed space having an inverted triangular shape when viewed from a vehicle side in which a space is gradually narrowed from an upper portion to a lower portion. Further, at the time of mounting, the rear rear-fender and the rear rear-fender bracket are coupled by being screwed together by rear winkers on sides of the vehicle (long holes). Further, a lower portion of the rear rear-fender and a lower portion of the rear rear-fender bracket are coupled by being screwed together by a license plate mounting bracket.

Abstract: An antiskid braking device for a motorcycle includes a single pump unit which is used to repressurize braking mechanisms of front and rear wheels of the motorcycle and mounted almost in a central portion of a body frame of the motorcycle and a master cylinder of the front wheel. Middle portions of front wheel brake pipes connecting the pump unit to the braking mechanisms are formed of metallic pipes, both ends of the metallic pipes are connected to the braking mechanisms, the master cylinder and the pump unit through flexible brake hoses, and the metallic pipes are arranged along an inside face of a pair of bilateral tank rails of the body frame extending rearward from a head pipe of the motorcycle. The pump unit is mounted so as to extend in a longitudinal dimension thereof along a longitudinal direction of the motorcycle and a brake pipe port section faces front and rear directions of the body of the motorcycle.
