To provide a motor cycle which achieves improvement of protection performance of a catalyst while inhibiting peripheral components of the catalyst from being thermally damaged by heat from the catalyst.SOLUTION: A motor cycle includes: a vehicle body frame 2; an engine 9 supported by the vehicle body frame 2; an exhaust pipe 86 in which exhaust gas exhausted from an exhaust port of the engine 9 flows; and a catalyst 81 which is provided within the exhaust pipe 86 and disposed in front of the engine 9; a vehicle body cover 14 which covers at least a part of the vehicle body frame 2 and covers at least a part of the catalyst 81 in a vehicle side view; and a louver 15 which connects both side parts 14R, 14L as seen in a lateral direction of the vehicle body cover 14 in front of the catalyst 81. The louver 15 includes multiple lateral ribs 152 extending in the lateral direction. The multiple lateral ribs 152 are provided forming a gap in a vertical direction. In a vehicle front view, at least parts of the one or multiple lateral ribs 152 overlap with the catalyst 81.SELECTED DRAWING: Figure 6

    【課題】触媒からの熱によって触媒の周辺部品が熱害を受けるのを抑制しつつ、触媒の保護性能を向上させる。【解決手段】自動二輪車は、車体フレーム2と、車体フレーム2に支持されるエンジン9と、エンジン9の排気口から排出される排気ガスが流れる排気管86と、排気管86内に設けられ、エンジン9の前方に配置される触媒81と、車体フレーム2の少なくとも一部を覆い、車両側面視で触媒81の少なくとも一部を覆う車体カバー14と、触媒81の前方で車体カバー14の左右方向両側部14R、14Lを繋ぐルーバー15と、を備え、ルーバー15は、左右方向に延びる複数の横リブ152を備え、複数の横リブ152は、上下方向に間隔をおいて設けられており、車両前面視で、一又は複数の横リブ152の少なくとも一部が触媒81と重なっている。【選択図】図6
