To propose an exhaust device which eases imbalance of a mass balance (a mass balance in a lateral direction of a vehicle) of the exhaust device and enables improvement of flexibility of balance adjustment between the exhaust device and components other than the exhaust device, and to propose a saddle-riding type vehicle.SOLUTION: An exhaust device 57 includes: an exhaust pipe 71 which guides exhaust air of an engine 11 mounted on a motor cycle 1; and a muffler 72 connected to a downstream end of the exhaust pipe 71. The exhaust pipe 71 includes: an upstream pipe part 75 connected to the engine 11 and disposed at one of left and right sides of the motor cycle 1; a traversing pipe part 76 which is connected to a downstream end 75b of the upstream pipe part 75 and extends, from one of the left and right sides of the motor cycle 1 to the other side, crossing a center line extending in an anteroposterior direction of the motor cycle 1 in a plan view; and a downstream pipe part 77 which is connected to a downstream end 76b of the traversing pipe part 76 and extends to the rear of the motor cycle 1.SELECTED DRAWING: Figure 4
【課題】排気装置そのものの質量バランス(車両の左右方向の質量バランス)の不均衡を緩和し、排気装置と排気装置以外の構成部品とのバランス調整の自由度を向上させる排気装置および鞍乗型車両を提案する。【解決手段】排気装置57は、自動二輪車1に搭載されるエンジン11の排気を導く排気管71と、前記排気管71の下流端に接続されるマフラー72と、を備えている。排気管71は、エンジン11に接続され、かつ自動二輪車1の左右いずれか一方側に配置される上流管部75と、上流管部75の下流端75bに連接され、かつ自動二輪車1の左右いずれか一方側から他方側へ向かって、平面視において自動二輪車1の前後方向に延びる中心線を跨がって延びる横断管部76と、横断管部76の下流端76bに連接され、自動二輪車1の後方へ延びる下流管部77と、を有している。【選択図】 図4
