Abstract: A snowmobile has a frame having a tunnel; at least one ski operatively connected to the frame; a motor supported by the frame; an endless drive track disposed at least in part below the tunnel and operatively connected to the motor for propulsion of the snowmobile; a suspension assembly operatively connected to the frame, the suspension assembly supporting and tensioning the endless drive track, the suspension assembly having a least one rear idler wheel, the at least one idler wheel defining an idler wheel rotation axis; and a snow guard connected to the suspension assembly. The snow guard has a deflector. The deflector has a leading edge and a trailing edge. The leading edge is rearward and upward of the idler wheel rotation axis. The trailing edge is rearward and upward of the idler wheel rotation axis.

Abstract: A snowmobile has a frame having a tunnel, an engine supported by the frame, at least one ski connected to the frame, a drive track operatively connected to the engine and disposed at least in part below the tunnel, and a fuel tank connected to a top of the tunnel. The fuel tank defines a passage extending therethrough from a top of the fuel tank to a bottom of the fuel tank. The passage is adapted for receiving a battery therein.

Abstract: A suspension assembly for a vehicle has left and right suspension arms, left and right shock absorbers operatively connected to their corresponding suspension arms, a sway bar operatively connected to the left and right suspension arms, left and right hinges pivotally connecting corresponding ends of the sway bar to their corresponding suspension arms. Each hinge includes a first hinge member pivotally connected to its corresponding end of the sway bar, a second hinge member pivotally connected to its corresponding suspension arm, the second hinge member being pivotally connected to the first hinge member, and a hinge lock selectively rigidly connecting the first hinge member to the second left member to prevent the first hinge member from pivoting relative to the second hinge member. A vehicle having the suspension assembly is also disclosed.

Abstract: A snowmobile is disclosed having a frame. A tunnel is formed in a rearward portion of the frame. An engine disposed on the frame. A drive track is disposed at least in part in the tunnel and is operatively connected to the engine for propulsion of the snowmobile. At least one ski is operatively connected to the frame at least in part forwardly of the drive track. A straddle seat is disposed on the frame at least in part above the drive track. A steering device is operatively connected to the at least one ski for steering the snowmobile. A radiator is disposed between the tunnel and the track. The radiator has a first side facing the track and a second side facing the tunnel. The second side is generally opposite the first side. At least a portion of the second side is spaced apart from the tunnel.

Abstract: A snowmobile is disclosed having a tunnel to accommodate and cover the drive track of the snowmobile underneath and to support the straddle seat of the snowmobile above. The tunnel includes portions interconnecting the sidewalls of the tunnel to the top portion of the tunnel and which provides clearances to fit a narrower straddle seat thereon thereby improving manoeuvrability and rider comfort. A straddle seat adapted to register with the tunnel is also disclosed.
