A vehicle body cooling structure for a motorcycle comprises a cooling air passage that extends between an engine and a fuel tank in the front-and-rear direction. A cowling covers the front part of the vehicle body, which contains the engine. The vehicle body cooling structure also comprises a heat blocking member that covers an upper part of the engine. The cooling air passage is separated into an engine side cooling air passage and a fuel tank side cooling air passage by the heat blocking member.

What is claimed is: 1. A motorcycle, the motorcycle comprising an engine, the engine comprising a cylinder that extends generally vertically, an air intake device being connected to the engine and supplying air to the engine for combustion in the cylinder, the air intake device comprising an air cleaner, a fuel tank disposed generally above the engine, a cooling air passage extending between the engine and the fuel tank in the front-and-rear direction, and a vehicle body cover covering a forward portion of the motorcycle and the engine, a heat blocking member covering an upper part of the engine, the heat blocking member being positioned between the cylinder and the fuel tank and being spaced apart from the air cleaner in a front-to-rear direction of the motorcycle, and the cooling air passage being separated into an engine side cooling air passage and a fuel tank side cooling air passage by the heat blocking member. 2. The motorcycle of claim 1, wherein air introduction ports are provided on a front surface of the vehicle body cover and the fuel tank side cooling air passage communicates with the air introduction ports. 3. The motorcycle according to claim 2, wherein head lights are provided at a laterally central portion of the front end of the vehicle body cover and the air introduction ports comprise first air introduction ports that are positioned along the laterally outer sides of the head lights. 4. The motorcycle according to claim 3, wherein the head lights are positioned substantially at the same vertical height as at least a portion of the fuel tank and upper and lower edges of the first air introduction ports are generally aligned with upper and lower edges of the head lights. 5. The motorcycle according to claim 3, wherein the motorcycle further comprises a left tank rail and a right tank rail, the fuel tank is mounted to the right and left tank rails, air introduction paths extending from the first air introduction ports toward the rear are positioned adjacent to laterally outer sides of the vehicle body cover; and rear ends of the air introduction paths extend toward a clearance formed between the right and left tank rails and the fuel tank. 6. The motorcycle according to claim 3, wherein the motorcycle further comprises a head pipe, a left tank rail and a right tank rail that extend rearward from the head pipe, the fuel tank being mounted to the left and right tank rails, and a cooling air introduction hole extends through the tank rails in the front-and-rear direction of the vehicle body, the air introduction hole being formed proximate a portion of the left and right tank rails that is connected with the head pipe. 7. The motorcycle according to claim 2, wherein head lights are provided at a laterally central portion of the front end of the vehicle body cover and the air introduction ports comprise second air introduction ports disposed generally above the head lights. 8. The motorcycle according to claim 7, wherein the vehicle body cover comprises a front cowling and an air introduction duct for guiding airflow generated by forward movement of the vehicle and introduced through the second air introduction ports into the front cowling is provided on the front cowling above the head lights. 9. The motorcycle according to claim 8, further comprising a separating member that separates a space between an upper end of the radiator and an upper part of the engine into upper and lower parts and the engine side cooling air passage comprises a lower passage positioned below the separating member and an upper passage positioned above the separating member. 10. The motorcycle according to claim 1, wherein a radiator is positioned forward of the engine and a front end of the heat blocking member is positioned generally above the radiator. 11. A vehicle body cooling structure for a motorcycle, the motorcycle comprising an engine, a fuel tank disposed generally above the engine, a cooling air passage extending between the engine and the fuel tank in the front-and-rear direction, and a vehicle body cover covering a forward portion of the motorcycle and the engine, the vehicle body cover comprising a front cowling, a heat blocking member covering an upper part of the engine and the cooling air passage being separated into an engine side cooling air passage and a fuel tank side cooling air passage by the heat blocking member, air introduction ports being provided on a front surface of the vehicle body cover and the fuel tank side cooling air passage communicating with the air introduction ports, head lights being provided at a laterally central portion of the front end of the vehicle body cover and the air introduction ports comprising second air introduction ports disposed generally above the head lights, an air introduction duct for guiding airflow generated by forward movement of the vehicle and introduced through the second air introduction ports into the front cowling being provided on the front cowling above the head lights, and a separating member that separates a space between an upper end of the radiator and an upper part of the engine into upper and lower parts and the engine side cooling air passage comprising a lower passage positioned below the separating member and an upper passage positioned above the separating member. 12. A motorcycle comprising the vehicle body cooling structure of claim 11.
