  • Patent number: 10336269
    Abstract: One embodiment provides a saddle-ride type vehicle. The vehicle includes a main frame; a drive source supported by a lower side of the main frame; an energy storing part supported by an upper side of the main frame; a front wheel steerably supported via a front fork mounted on a front side of the main frame; a rear wheel supported via a swing arm mounted on a rear side of the main frame and configured to be driven by the drive source; and seat frames disposed on the rear side of the main frame to support a riding seat. A braking control device is disposed within a lateral width between the seat frames, and is supported by a rear fender supported by the seat frame via a vibration control member. And, an inertia measuring device is supported by the braking control device.

  • Publication number: 20190085744
    Abstract: An exhaust muffler includes a first muffler section having a tubular member made up of an inner pipe to which an exhaust pipe is connected and an outer pipe covering the inner pipe, and a connector connecting the tubular member and a second muffler section to each other, and the second muffler section having an outer shell, a first partition wall, a second partition wall, and a third partition wall. Exhaust gases delivered from the exhaust pipe are discharged from the first muffler section and the second muffler section out of the exhaust muffler. The second muffler section has a cross-sectional area larger than a cross-sectional area of the tubular member. The exhaust muffler includes a first expansion chamber, a second expansion chamber, and a third expansion chamber.

  • Publication number: 20190078476
    Abstract: An exhaust muffler is made up of a plurality of layers including an exhaust passage pipe and expansion chambers, and includes a front assembly and a rear assembly sub-assembled separately from the front assembly. The front assembly includes a front exhaust passage pipe, a front muffler body disposed in covering relation to the outside of the front exhaust passage pipe and cooperating with the front exhaust passage pipe in making up double-walled pipes, and an exhaust valve disposed in the front exhaust passage pipe. The rear assembly includes a rear exhaust passage pipe and a rear muffler body disposed in covering relation to the outside of the rear exhaust passage pipe and cooperating with the rear exhaust passage pipe in making up double-walled pipes. There is thus provided an exhaust device for an internal combustion engine in which the accuracy of a position where the exhaust valve is installed is high.

  • Publication number: 20190055866
    Abstract: An exhaust muffler includes a first muffler section connected to an exhaust pipe and a second muffler section connected to the first muffler section. Exhaust gases delivered from the exhaust pipe are discharged from the first muffler section and the second muffler section out of the exhaust muffler. The first muffler section includes a tubular member made up of an inner pipe to which the exhaust pipe is connected and an outer pipe covering the inner pipe, and a connector connecting the tubular member and the second muffler section to each other. The first muffler section has a first expansion chamber defined therein between the inner pipe and the outer pipe. The inner pipe houses therein a valve for changing an amount of exhaust gases passing through the inner pipe. The first muffler section includes a curved portion that is curved vertically as viewed in side elevation of the vehicle.

  • Patent number: 8689923
    Abstract: A saddle riding vehicle includes a vehicle body frame, a front wheel, a rear wheel, a power unit, a shift actuator, and an actuator guard. The power unit has a transmission and a shift mechanism for the transmission. The shift actuator is to actuate the shift mechanism and is attached to a lower portion of a side face of the power unit. The actuator guard is to protect the shift actuator from an obstacle and includes a guard frame and a guard member. The guard frame extends in a forward and backward direction of the saddle riding vehicle below the shift actuator. The guard frame is connected to the vehicle body frame. The guard member is connected to the guard frame and covers a lower face and an outer side face of the shift actuator.
