The application also provides a motorcycle, especially a cross-country motorcycle, the motorcycle includes the automobile body and as above the motorcycle canister protection configuration structure, this motorcycle canister protection configuration structure locates on the automobile body, makes this motorcycle can realize the protection to canister 2 through the part, avoids flying stone, muddy water, grass etc. to canister 2's damage. Meanwhile, the motorcycle has compact integral space and high utilization rate of the whole motorcycle, and is popular with users.

The foregoing is only a preferred embodiment of the present application, and it should be noted that, for those skilled in the art, several modifications and substitutions can be made without departing from the technical principle of the present application, and these modifications and substitutions should also be regarded as the protection scope of the present application.
