PROBLEM TO BE SOLVED: To provide a saddle-riding type vehicle capable of reducing an impact of hot air of a catalysis on vehicle components, while performing an early stage activation of the catalysis.SOLUTION: A saddle-riding type vehicle comprises: a vehicle body frame; a single cylinder 4-stroke engine unit including a horizontal cylinder part 96 and a crank case part which are arranged so that a cylinder axis is aligned in a horizontal direction; oscillation support parts 105, 106, 108, 109 disposed in the single cylinder 4-stroke engine unit, and oscillatably supported by the vehicle body frame; and a main catalysis 100, which has a passage direction length longer than a maximum width in a direction perpendicular to the passage direction, an exhaust gas purification capability highest in an exhaust passage, and which is disposed in the left of a left end or the right of a right end of the oscillation support parts in a lateral direction of the saddle-riding type vehicle 80, and which is arranged to overlap at least a part of the oscillation support parts 105, 106, 108, 109 in a side view, and to overlap at least a part of the single cylinder 4-stroke engine unit in a top view or in a bottom view.SELECTED DRAWING: Figure 4 【課題】触媒の早期活性化を図りつつ、触媒の熱気による車両部品への影響を低減できる鞍乗型車両を提供する。【解決手段】車体フレームと、シリンダ軸線が水平方向を向くように設けられた水平シリンダ部９６およびクランクケース部を含む単気筒４ストロークエンジンユニットと、単気筒４ストロークエンジンユニットに設けられ、車体フレームに揺動可能に支持される揺動支持部１０５、１０６、１０８、１０９と、通路方向の長さが、通路方向に直交する方向の最大幅より長く、排気通路内で排ガスの浄化能力が最も高く、鞍乗型車両８０の左右方向において、揺動支持部の左端の左方または右端の右方に配置され、側面視で揺動支持部１０５、１０６、１０８、１０９と少なくとも一部が重なり、且つ、上面視または下面視で単気筒４ストロークエンジンユニットと一部が重なるように配置されたメイン触媒１００と、を備える構成を採る。【選択図】図４
