Abstract

An off-road vehicle having a frame, a plurality of ground engaging members operably coupled to the frame, a seat supported by the frame and configured to support an operator, an engine supported by the frame, a body supported by the frame, and a liner coupled to the body, where the liner is configured to be positioned between the body and a heat source of the off-road vehicle, and an air gap extends between the liner and the body.

First claim

What is claimed is:

1. An off-road vehicle, comprising:
a frame;
a plurality of ground engaging members operably coupled to the frame;
a straddle seat supported by the frame and configured to support an operator;
an engine supported by the frame;
a body supported by the frame; and
a liner having a liner body coupled to the body, the liner configured to be positioned between the body and a heat source of the off-road vehicle, wherein an air gap extends from an inner surface of the liner body to an inner surface of the body, wherein an outer surface of the body defines an exterior surface of the off-road vehicle and an outer surface of the liner is adjacent the heat source.

2. The off-road vehicle of claim 1 , wherein the liner includes a body and at least one tab.

3. The off-road vehicle of claim 2 , wherein the body of the off-road vehicle includes at least one tab, the at least one tab of the liner being positioned between the at least one tab of the body and the frame.

4. The off-road vehicle of claim 1 , wherein the liner includes an inlet configured to flow fluid through the air gap, the body including a lip spaced apart from the inlet and configured to protect the inlet, the lip extending downward past the inlet.

5. The off-road vehicle of claim 4 , wherein the liner includes an indented portion along an outward facing edge of the liner, the inlet being positioned along the indented portion.

6. The off-road vehicle of claim 1 , wherein the air gap is exposed along a side of the body and a side of the liner.

7. The off-road vehicle of claim 1 , wherein the liner further includes a drip shield configured to route at least one of liquid and debris away from the heat source.

8. The off-road vehicle of claim 7 , wherein the drip shield includes at least one flange and a spout.

9. The off-road vehicle of claim 1 , wherein at least one heat shield is coupled to the liner.

10. The off-road vehicle of claim 9 , wherein the at least one heat shield and the liner are formed of a single, unitary piece.

11. The off-road vehicle of claim 1 , wherein the at least one heat shield is positioned between the liner and the heat source.

12. The off-road vehicle of claim 1 , wherein the air gap is approximately 5-10 millimeters wide.

13. The off-road vehicle of claim 1 , wherein the body and the liner are a single, unitary piece.

14. The off-road vehicle of claim 1 , wherein the liner creates an inlet when coupled to the body.

15. A vehicle, comprising:
a frame;
a plurality of ground engaging members operably coupled to the frame;
an operator seat supported by the frame, the operator seat configured to support at least one user;
an engine supported by the frame; and
a body supported by the frame, the body having a first portion and a second portion, the first portion being spaced apart from the second portion in a configuration defining an air gap between the first portion and the second portion, the first portion defining a portion of an outer surface of the body, wherein the second portion includes an inlet configured to flow fluid through the air gap and the first portion includes a lip spaced apart from the inlet and configured to protect the inlet.

16. The vehicle of claim 15 , wherein the second portion of the body is removably coupled to the first portion of the body.

17. The vehicle of claim 15 , wherein the air gap between the first portion and the second portion is configured to allow temperatures at an upper surface of the body to be reduced to below 66 degrees Centigrade.

18. The vehicle of claim 15 , wherein the first portion and the second portion are positioned adjacent an exhaust of the engine, the second portion being positioned between the exhaust and the first portion.

19. The vehicle of claim 15 , wherein the lip extends downward past the inlet.

20. The vehicle of claim 15 , wherein at least a portion of the second portion is positioned between the frame and at least a portion of the first portion.

21. An off-road vehicle, comprising:
a frame;
a plurality of ground engaging members operably coupled to the frame;
a straddle seat supported by the frame and configured to support an operator;
an engine supported by the frame;
a body supported by the frame, at least a portion of the body defining an exterior surface of the off-road vehicle; and
a liner coupled to the body and configured to be positioned between the body and a heat source of the off-road vehicle, wherein an air gap extends between the liner and the body, and the heat source has a longitudinal length and a lateral width, the liner extending continuously at least along the lateral width of the heat source.

22. The off-road vehicle of claim 21 , wherein at least a portion of an outer surface of the body is adjacent the straddle seat and exposed to an external environment.

23. The off-road vehicle of claim 21 , wherein the liner extends continuously along the longitudinal length of the heat source.

24. The off-road vehicle of claim 21 , wherein the heat source is a muffler.

25. The off-road vehicle of claim 21 , wherein the liner extends between the straddle seat and an outer edge of the off-road vehicle.

26. The off-road vehicle of claim 21 , wherein a lateral width of the liner is different from a lateral width of the body.

27. The off-road vehicle of claim 21 , wherein the liner includes an inlet, the inlet positioned along an indented section of the liner and extending away from the body.
