Abstract: An extended movement rear suspension for a snowmobile. The suspension includes at least two elongated members of a substantially constant length coupled to the snowmobile frame and to an endless track guide rail assembly. The suspension configures the endless track into a generally triangular shape.
Abstract: A extended movement rear suspension for a snowmobile. The suspension includes at least two elongated members of a substantially constant length coupled to the snowmobile frame and to an endless track guide rail assembly. The suspension keeps the guide rail assembly at a substantially constant angular orientation relative to the frame for improved performance and operator comfort. The suspension also configures the endless track into a generally triangular shape.
