Abstract

In a saddle-ride type vehicle in which a cylinder includes a cylinder head and a cylinder head cover that covers an upper portion of the cylinder head, a vehicle body frame includes a head cover adjoining portion that adjoins the cylinder head cover. At least a part of the cylinder head cover overlaps the head cover adjoining portion as viewed from a direction along a cylinder axis that is a center axis of the cylinder. The head cover adjoining portion extends rearward such that the cylinder head cover is exposed outside in a side view. The foregoing configuration seeks to affect the ease of mounting and dismounting a saddle-ride vehicle having a power unit with a cylinder arranged upward and the vehicle body frame for supporting the power unit by reducing the left-right width of a vehicle body frame while allowing a cylinder head cover to be attachable and detachable.

First claim

The invention claimed is:

1. A saddle-ride type vehicle comprising:
a power unit having a cylinder arranged upward; and
a vehicle body frame supporting the power unit,
wherein:
the cylinder includes a cylinder head and a cylinder head cover that covers an upper portion of the cylinder head,
the vehicle body frame is divided into a main frame as a vehicle front frame and a seat rail as a vehicle rear frame,
the seat rail is fixed on a front side and a rear side thereof in a front-rear direction of the vehicle above the cylinder head cover with respect to a cylinder axis which is a center axis of the cylinder,
the seat rail has a head cover adjoining portion that is adjacent so as to straddle over the cylinder head cover,
at least a part of the cylinder head cover overlaps the head cover adjoining portion as viewed from a direction along the cylinder axis,
the head cover adjoining portion extends rearward such that the cylinder head cover is exposed outside in a side view,
a gap is formed between the head cover adjoining portion and the cylinder head cover in a side view, and
the gap is narrower than a height of the cylinder head cover in the direction of the cylinder axis in a side view.

2. The saddle-ride type vehicle according to claim 1 , further comprising a seat that allows an occupant to be seated,
wherein the head cover adjoining portion of the seat rail is divided into left and right head cover adjoining portions which are provided and disposed below the seat.

3. The saddle-ride type vehicle according to claim 2 ,
wherein the seat rail supports the seat, and
the head cover adjoining portions of the seat rail adjoin the cylinder head cover.

4. The saddle-ride type vehicle according to claim 3 ,
wherein the cylinder head cover includes a cylinder head cover body that covers the upper portion of the cylinder head and a flange protruding outward along an outer periphery of the cylinder head cover body as viewed from the direction along the cylinder axis, and
at least a part of the flange overlaps the head cover adjoining portions as viewed from the direction along the cylinder head axis.

5. The saddle-ride type vehicle according to claim 4 , wherein the power unit includes a V-type engine having a rear cylinder inclining rearward and upward as the cylinder.

6. The saddle-ride type vehicle according to claim 2 , wherein an outer wall on an outside of each of the head cover adjoining portions in a vehicle width direction includes a chamfer inclining inward in the vehicle width direction toward a lower side thereof.

7. The saddle-ride type vehicle according to claim 6 ,
wherein the seat rail supports the seat, and the head cover adjoining portions of the seat rail adjoin the cylinder head cover.

8. The saddle-ride type vehicle according to claim 7 ,
wherein the cylinder head cover includes a cylinder head cover body that covers the upper portion of the cylinder head and a flange protruding outward along an outer periphery of the cylinder head cover body as viewed from the direction along the cylinder axis, and
at least a part of the flange overlaps the head cover adjoining portions as viewed from the direction along the cylinder head axis.

9. The saddle-ride type vehicle according to claim 8 , wherein the power unit includes a V-type engine having a rear cylinder inclining rearward and upward as the cylinder.

10. The saddle-ride type vehicle according to claim 6 ,
wherein the cylinder head cover includes a cylinder head cover body that covers the upper portion of the cylinder head and a flange protruding outward along an outer periphery of the cylinder head cover body as viewed from the direction along the cylinder axis, and
at least a part of the flange overlaps the head cover adjoining portions as viewed from the direction along the cylinder head axis.

11. The saddle-ride type vehicle according to claim 1 ,
wherein the cylinder head cover includes a cylinder head cover body that covers the upper portion of the cylinder head and a flange protruding outward along an outer periphery of the cylinder head cover body as viewed from the direction along the cylinder axis, and
at least a part of the flange overlaps the head cover adjoining portion as viewed from the direction along the cylinder head axis.

12. The saddle-ride type vehicle according to claim 1 , wherein the power unit includes a V-type engine having a rear cylinder inclining rearward and upward as the cylinder.

13. The saddle-ride type vehicle according to claim 2 ,
wherein the cylinder head cover includes a cylinder head cover body that covers the upper portion of the cylinder head and a flange protruding outward along an outer periphery of the cylinder head cover body as viewed from the direction along the cylinder axis, and
at least a part of the flange overlaps the head cover adjoining portions as viewed from the direction along the cylinder head axis.

14. The saddle-ride type vehicle according to claim 13 , wherein the power unit includes a V-type engine having a rear cylinder inclining rearward and upward as the cylinder.
