An intake pipe is provided in a center area in a width direction and extends rearward across and beyond an upper cross member. Left and right seat rails are provided on opposite sides of the intake pipe, and are connected to left and right main frames at portions forward of a point at which the intake pipe exceeds the upper cross member in height.

  • Patent number: 7533904
    Abstract: A fuel pump for a vehicle is resistant to damage and effectively uses fuel in a fuel tank. The fuel tank is saddle-shaped and straddles an upper side frame section of the vehicle. A left side tank section extends downward on a left side of the upper side frame section and a right side tank section extends downward on a right side. A fuel pump in the interior of the fuel tank is fixed on the bottom surface of either the left or right side tank section. For off-road saddle-riding type vehicles, the fuel pump is provided anterior to a fuel tank central portion when viewed from a side of the vehicle to ensure easy handling and foot landing properties.

  • Publication number: 20080223648
    Abstract: A body frame of a motorcycle in which strength and rigidity against external forces are secured while increased cost is suppressed. A mainframe has an upper bearing and a pipe main body of a head pipe and is extended rearward. A down tube includes a first tube having a lower bearing of the head pipe and extended rearward and second tubes joining the first tube and bosses of the mainframe. The first tube is joined to the mainframe by welding, and the second tubes are detachably joined to the first tube.

  • Publication number: 20070023225
    Abstract: A saddle-type vehicle in which contact with a hot exhaust pipe is prevented and transfer of the heat of the exhaust pipe is effectively interrupted. The exhaust pipe is disposed on the side of the engine, for guiding exhaust gas emitted from the engine. An exhaust pipe cover interrupts heat generated from the exhaust pipe. The exhaust pipe cover is disposed apart from the exhaust pipe and covers at least part of the exhaust pipe. The exhaust pipe cover has supported portions supported by a crankcase.
