Abstract

The air intake structure for a saddle-ride type vehicle includes a front cowl, a pair of right and left air duct portions, an air cleaner box, and a vehicle body frame. The front cowl includes a pair of right and left air intake ports. The pair of the right and left air duct portions guides air taken from the pair of the right and left air intake ports. The air cleaner box cleans the air guided by the pair of the right and left air duct portions. The vehicle body frame is branched backward from a steering head pipe disposed on a front side of a vehicle into a bifurcated shape with a pair of right and left. The vehicle body frame includes the air cleaner box between the branches of the bifurcated shape. The air duct portion includes a first air duct and a second air duct. The first air duct guides air to the air cleaner box from the air intake port through the vehicle body frame. The second air duct branches from the first air duct in a middle to guide air to the air cleaner box.

First claim

What is claimed is:

1 . An air intake structure for a saddle-ride type vehicle, comprising:
a front cowl that includes a pair of right and left air intake ports; a pair of right and left air duct portions that guides air, the air being taken from the pair of the right and left air intake ports; an air cleaner box that cleans the air guided by the pair of the right and left air duct portions; and a vehicle body frame that is branched backward from a steering head pipe into a bifurcated shape with a pair of right and left, the steering head pipe being disposed on a front side of a vehicle, the vehicle body frame including the air cleaner box between branches of the bifurcated shape, wherein the air duct portion includes: a first air duct that guides air to the air cleaner box from the air intake port through the vehicle body frame, and a second air duct that branches from the first air duct in a middle to guide air to the air cleaner box.

2 . The air intake structure for a saddle-ride type vehicle according to claim 1 , further comprising:
a pair of right and left front forks that rotatably support a front wheel, wherein the vehicle body frame includes a pair of right and left first holes, and a pair of right and left second holes that are disposed between the pair of right and left first holes, the first air duct guides air to the air cleaner box through the first holes, and the second air duct is inserted between the pair of right and left front forks, and guides air to the air cleaner box through the second holes.

3 . The air intake structure for a saddle-ride type vehicle according to claim 1 , wherein
the first air duct includes a branch hole on a top surface, the second air duct includes an opening that communicates with the branch hole, and the opening obliquely opens forward and downward.

4 . The air intake structure for a saddle-ride type vehicle according to claim 1 , further comprising:
a brace that is fixed to the steering head pipe and supports a meter unit, wherein the second air duct is disposed on both right and left sides across the brace.
