Saddle ride type vehicle

摘要

An intake system includes an air cleaner arranged behind the cross member with a shock absorber supporting portion supporting an upper end of a rear shock absorber unit connected to an engine main body in such a manner wherein a straddling portion is curved in a shape convex upwardly to straddle the cross member and also the shock absorber supporting portion from above. A fuel injection valve for the intake system is arranged in front of the cross member. An intake passage is formed to extend linearly downwardly and to the front toward an intake port at a downstream side of a straddling portion. An upper portion of a passage forming member forming at least a part of the straddling portion by forming an apex part of the straddling portion is provided with a second fuel injection valve attached with its fuel injection direction directed to the intake port.
