    Abstract: A snowmobile includes a forward frame assembly defining an engine bay. An engine is positioned within the engine bay. The engine has a plurality of intake ports positioned on an aft side of the engine and a plurality of exhaust ports positioned on a forward side of the engine. An air intake system has at least one air inlet and a plurality of air outlets. The air intake system is coupled to the aft side of the engine such that each of the air outlets is configured to provide air to one of the intake ports. An exhaust system has a plurality of exhaust inlets and at least one exhaust outlet. The exhaust system is coupled to the forward side of the engine such that each of the exhaust inlets is configured to receive exhaust from one of the exhaust ports.

    Abstract: A running board assembly for a snow vehicle includes a support member positioned outboard from a tunnel of the snow vehicle. The support member includes a first end, a second end, and an attachment element located intermediate of the first end and the second end. One or more foot support members is disposed inboard from the support member. A support leg is removably securable to the attachment element of the support member. The support leg includes a mounting feature securable to a rear suspension component disposed below an upper surface of a drive track.

    Abstract: A steering system for a snowmobile includes a handlebar assembly and a steering column that has an upper end coupled to the handlebar assembly. An electronic steering assist unit is coupled to the steering column between upper and lower posts of the steering column. A steering arm assembly is coupled to a lower end of the lower post. First and second tie rods respectively couple the steering arm assembly to first and second ski assemblies such that turning the handlebar assembly, together with the assistance of the electronic steering assist unit, causes the ski assemblies to pivot. A floating mounting system couples the electronic steering assist unit to forward spars of the frame assembly to prevent a torque pre-load on the electronic steering assist unit. The steering column and the electronic steering assist unit share a common axis of rotation that is positioned along a centerline of the snowmobile.

    Abstract: An exhaust system for a snowmobile includes a muffler housing, the bottom end of the muffler housing including a muffler exhaust outlet configured to emit exhaust. The exhaust system includes a muffler housing cover spaced from the muffler housing to define an airflow channel therebetween, the muffler housing cover forming a bottom opening. The exhaust system also includes a gas combiner at least partially surrounding the muffler exhaust outlet on the bottom end of the muffler housing and extending through the bottom opening of the muffler housing cover. The gas combiner receives air from the airflow channel and the exhaust from the muffler exhaust outlet to emit a combined air-exhaust stream.
