An all terrain vehicle has a lubrication system that draws from an oil pan and lubricates the main bearings and the piston. A drive shaft for the vehicle is positioned outside of the oil pan such that the oil pan's lateral dimension may be decreased. Additionally, a lubricant pump pickup is located within a recess in the bottom of the oil pan such that the pick-up is at about the same vertical height as the lower surface of the crankcase. The vehicle is also shiftable from two-wheel drive to four-wheel drive. The shifting mechanism is located within the crankcase or transmission case. A locking collar selectively engages or disengages two of the four wheels from the output.
