Abstract

Left and right radiators in a saddle type vehicle are formed in a trapezoidal shape and disposed such that a shorter one of two side portions of each of the radiators which extend in parallel or substantially in parallel to each other as viewed in front elevation is positioned at the inner side in the vehicle widthwise direction. A longer one of the side portions is disposed at the outer side in the vehicle widthwise direction. Forward projections of an exhaust pipe projecting forwardly from an engine pass below the shorter side portions at the inner side in the vehicle widthwise direction of the radiators.

First claim

The invention claimed is:

1. A saddle type vehicle, comprising:
left and right main frames extending rearwardly from a head pipe;
a down frame extending downwardly from the head pipe;
an engine disposed below the left and right main frames in a rear of the down frame, and a pair of left and right radiators attached to the down frame; and
an exhaust pipe connected to the engine includes left and right forward projections extending forwardly from the engine, passing a left and right of the down frame and being curved downwardly, wherein
at least one of the left and right radiators is formed in a trapezoidal shape, and the one of the radiators which is formed in the trapezoidal shape is disposed in a state in which, as viewed in front elevation, a shorter one of two side portions extending in parallel or substantially in parallel to each other is positioned at an inner side in a vehicle widthwise direction, and a longer one of the side portions is disposed at an outer side in the vehicle widthwise direction, and wherein
the forward projection positioned at a same side as the radiator formed in the trapezoidal shape is placed in a state in which the forward projection passes below the shorter side portion at the inner side in the vehicle widthwise direction of the radiator formed in the trapezoidal shape.

2. The saddle type vehicle according to claim 1 , wherein the lower ends of the radiators are positioned higher than a front face upper end of a crankcase of the engine.

3. The saddle type vehicle according to claim 1 , wherein
the left and right radiators are formed in a trapezoidal shape,
each of the left and right radiators includes radiator main body having a plurality of water pipes and a plurality of fins and a radiator grill disposed in front of the radiator main body, and wherein
the radiator main bodies and the radiator grills are formed in a plate-like shape and integrated in a state in which the radiator main bodies and the radiator grills extend along each other, and the radiator main bodies and the radiator grills are disposed in a state in which the radiator main bodies and the radiator grills extend to the outer sides in the vehicle widthwise direction as the radiator main bodies and the radiator grills ( 38 L and 38 R) extend forwardly as viewed in top plan.

4. The saddle type vehicle according to claim 3 , wherein
the radiator main bodies are configured such that the water pipes are disposed in a juxtaposed relationship in the vehicle widthwise direction in a state in which the water pipes extend in an upward and downward direction, and the water pipes are formed longer toward the outer sides in the vehicle widthwise direction,
each of the radiator main bodies includes an upper tank to which a hose for passing cooling water therethrough is connected and which is communicated with upper ends of the water pipes and a lower tank to which a hose for passing cooling water therethrough is connected and which is communicated with lower ends of the water pipes, the cooling water which enters the upper tanks entering the lower tanks through the water pipes, and wherein
the upper tanks and the lower tanks are configured such that the height thereof in the upward and downward direction and the capacity of a portion thereof at the outer side in the vehicle widthwise direction are set higher and greater than those of a portion thereof at the inner side in the vehicle widthwise direction.

5. The saddle type vehicle according to claim 3 , wherein
each of the left and right radiators includes a radiator shroud disposed in the rear of the radiator main body, and wherein
the radiator shroud has a first opening provided at one end portion thereof and is integrated with the radiator main body by fitting the first opening with a first projection provided on the radiator main body and fitting a first fastening member to the other end portion of the radiator shroud at the opposite side to the one end portion to fasten the radiator shroud to the radiator main body.

6. The saddle type vehicle according to claim 3 , wherein
each of the radiator grills has a second opening provided at one end portion thereof and a third projection provided at the other end portion thereof at the opposite side of the one end portion, and is integrated with the radiator main body by inserting a second projection provided on the radiator main body into the second opening and inserting the third projection into a third opening formed on the radiator main body.

7. The saddle type vehicle according to claim 5 , wherein
each of the radiator grills has a second opening provided at one end portion thereof and a third projection provided at the other end portion thereof at the opposite side to the one end portion, and is integrated with the radiator main body by inserting a second projection provided on the radiator main body into the second opening and inserting the third projection into a third opening formed on the radiator main body,
one of the first projection and the second projection provided on the radiator main body is provided at the inner side in the vehicle widthwise direction and the other one of the first and second projections is provided at the outer side in the vehicle widthwise direction, and wherein
the first opening provided at the one end portion of the radiator shroud and the second opening provided at the one end portion of the radiator grill are spaced to the inner side and the outer side in the vehicle widthwise direction.

8. The saddle type vehicle according to claim 3 , wherein
an oil cooler is attached to one of the left and right radiators and a radiator reserve tank is attached to the other one of the left and right radiators.

9. The saddle type vehicle according to claim 8 , wherein
the radiator reserve tank has a projection inserted in an opening provided at an upper portion of the radiator grill and a fastening portion fastened to a front cowl stay disposed in front of the head pipe, and is supported on the radiator grill and the front cowl stay by inserting the projection into the opening and fastening the fastening portion to the front cowl stay.

10. The saddle type vehicle according to claim 1 , wherein
a pair of left and right reinforcing members are provided across the left and right main frames and the down frame, and wherein
the reinforcing member positioned at the same side as the radiator formed in the trapezoidal shape is in a state in which the reinforcing member passes above the shorter side portion at the inner side in the vehicle widthwise direction of the radiator formed in the trapezoidal shape.

11. The saddle type vehicle according to claim 10 , wherein
upper portions of the left and right radiators are connected to each other by a radiator connection hose through which cooling water is circulated, and wherein
the radiator connection hose is disposed in the rear of the down frame below the reinforcing members.

12. The saddle type vehicle according to claim 10 , wherein
a radiator feeding hose for feeding cooling water from the engine therethrough is connected to an upper portion of one of the left and right radiators, and wherein
the radiator feeding hose is disposed in a state in which the radiator feeding hose overlaps with at least part of the reinforcing members as viewed in side elevation.

13. The saddle type vehicle according to claim 1 , wherein
each of the left and right radiators includes a radiator main body having a plurality of water pipes and a plurality of fins and a radiator shroud disposed in the rear of the radiator main body,
