Title: SADDLE-TYPE VEHICLE
Abstract:
Provided is a saddle-type vehicle comprising a unit swing engine 13 that is swingably supported on a vehicle body frame 12 via a link member 38, and an exhaust device 120 equipped with an exhaust pipe 121 and a catalyst device 140, wherein: the link member 38 is disposed above a crank case 34; at least a portion of the catalyst device 140 is disposed below a cylinder part 35 when viewed from a side surface; and an exhaust device coupling part 135 is positioned in a region between a virtual line L1 connecting the front end of the crank case 34 and a link member coupling part 61 that couples the link member 38 to the vehicle body frame 12 and a virtual line L2 connecting the link member coupling part 61 and an exhaust pipe connection part 35e of the unit swing engine 13 to which an end of the exhaust pipe 121 is connected, the exhaust device coupling part coupling the crank case 34 and the exhaust device 120. Due to this configuration, the degree of freedom in the arrangement of the catalyst device can be improved so that the catalyst device can be arranged in a compact manner, and the catalyst device can be stably and firmly supported even if the exhaust device or the catalyst device swings together with the unit swing engine.
