• a sprocket wheel engagable with the power plant of the vehicle, the sprocket wheel having a rotational axis, a perimetrical surface, and first and second axial surfaces;
• a first plurality of teeth extending radially outwardly from the perimetrical surface in spaced-apart relation;
• and
• a second plurality of teeth extending axially outwardly from the first axial surface in spaced-apart relation,
• wherein each tooth of the first plurality of teeth is formed on an outer surface of a corresponding tooth of the second plurality of teeth.

A vehicle comprising:

• a frame;
• a power plant supported by the frame;
• a sprocket operatively connected to the power plant, the sprocket comprising
• a sprocket wheel rotationally supported by the frame and operatively connected to the power plant, the sprocket wheel having a rotational axis, a perimetrical surface, and first and second axial surfaces,
• a first plurality of sprocket teeth extending radially outwardly from the perimetrical surface in spaced-apart relation,
• a second plurality of sprocket teeth extending axially outwardly from the first axial surface in spaced-apart relation, and
• a third plurality of sprocket teeth extending axially outwardly from the second axial surface in spaced-apart relation;
• and
• an endless track supported by the frame, the endless track passing around and engaging the sprocket.
