Abstract: A snowmobile is provided that includes rearward portion comprising at least one vehicle component (e.g., a seat, or a fuel tank). The snowmobile also includes an exhaust pipe, a radiator, a fan, and a duct. The exhaust pipe extends from an engine compartment in a forward portion to the rearward portion of the snowmobile. The radiator is positioned in the engine compartment. The fan is positioned near the radiator and the duct is provided on a rear side of the fan. The duct extends from the engine compartment to the rearward portion of the snowmobile. The fan and the duct cause air to pass through the radiator and to be discharged outside of the engine compartment. The duct is located between the exhaust pipe and the at least one vehicle component.

Abstract: An exhaust system for a snowmobile is provided. The exhaust system has an exhaust pipe that extends above a track belt from an engine to a rearward portion of the snowmobile. The exhaust pipe includes a tail pipe having an outlet to the atmosphere. The rearward portion of the snowmobile includes a space that has an opening that faces the track belt. The tail pipe is located in the space.

Abstract: A snowmobile has a body frame. A rear frame is coupled with the body frame. The rear frame defines a generally horizontally extending bottom section. Side sections generally vertically extend from side portions of the bottom section. A rear section generally vertically extends from a rear portion of the bottom section. The bottom, side and rear sections are unitarily formed by a casting process or a press working.

Abstract: A snowmobile has a body frame. A front frame is coupled with the body frame. The front frame is made of a casting. A pair of swing units are swingably supported by the front frame at first ends of the swing units. A pair of skis are supported by the swing units at second ends of the skies. A pair of suspension assemblies are connected with the front frame at first ends of the suspension assemblies. The suspension assemblies also are connected with the second ends of the swing units at second ends of the suspension assemblies.

Abstract: A snowmobile has a frame assembly. A drive assembly depends from the frame assembly and abuts the terrain. An engine powers the drive assembly. The engine includes an output shaft. A transmiss0n assembly transfers power of the engine to the drive assembly. The transmission assembly includes a transfer shaft driven by the output shaft. The frame assembly has a frame member disposed rearward of the engine. The frame member unitarily forms side sections, a rear section and a bottom section. The transfer shaft transversely extends between the side sections and is journaled by the side sections. The frame member supports the engine in front of the transfer shaft.

Abstract: A snowmobile is provided including an internal combustion engine, an induction system communicating with the engine, and a body defining an engine compartment in which the engine is at least in part contained. The body of the snowmobile includes at least two openings which communicate with the induction system, and a door movably positioned at at least one of the openings. The door is adapted to selectively open and close the opening to regulate a flow of induction air through the opening.
