A snowmobile providing an enhanced riding experience is disclosed. A snowmobile in accordance with the present invention may include a frame defining a tunnel and a track rotatably supported by the frame. The snowmobile may also include an engine connected to the frame and operatively coupled to the track by a drivetrain. A seat may be fixed to the frame for receiving a rider of the snowmobile. A pair of handle bars may be rotatably coupled to the frame and adapted to receive the hands of the rider. A pair of floor boards may be fixed to the frame and adapted to receive the feet of the rider. In some embodiments, the floor boards include toe stops which intersect the floor boards at an intersection.
