Straddled vehicle

A straddled vehicle comprising:

• a vehicle body frame;
• and
• an engine unit supported by the vehicle body frame, the engine unit including:
• an engine body having a cylinder head, through which exhaust gas flows out;
• a turbocharger configured to compress intake air using the exhaust gas flowed out from the engine body, and to supply the intake air to the engine body;
• and
• an exhaust device, including:
• an exhaust pipe and a muffler that are connected to each other to form a portion of an exhaust passage through which the exhaust gas passes, the portion allowing the exhaust gas passed through the turbocharger to pass therethrough, and
• a plurality of catalysts including a first catalyst and a second catalyst that are arranged in this order along a direction in which the exhaust gas flows through the exhaust pipe, wherein:
• the exhaust pipe has an upstream end thereof connected to the turbocharger, and a downstream end thereof connected to the muffler,
• the exhaust pipe includes a corner section that is bent in at least a part thereof between a downstream end of the first catalyst and an upstream end of the second catalyst, the plurality of the catalysts not being arranged in the corner section,
• a volume of the second catalyst is more than or equal to half of a volume of the first catalyst, and
• the exhaust pipe has an exhaust pipe internal area that is defined as a cross-sectional area of an internal space of the exhaust pipe orthogonal to the direction in which the exhaust gas flows, a maximum value of the exhaust pipe internal area between the upstream end of the exhaust pipe and an upstream end of the first catalyst being more than or equal to a maximum value of the exhaust pipe internal area between the upstream end of the first catalyst and the downstream end of the first catalyst, a maximum value of the exhaust pipe internal area between the downstream end of the first catalyst and the upstream end of the second catalyst being more than or equal to a maximum value of the exhaust pipe internal area between the upstream end of the second catalyst and a downstream end of the second catalyst.
