Zusammenfassung:	Provided herein are crankshafts comprising a first and second bearing journal both aligned along a crankshaft rotation axis, a first counterweight throw, a web throw including a first web and a second web coupled via a second crankpin, wherein the first web is coupled to the first counterweight throw via the first bearing journal, and a second counterweight throw coupled to the second web via the second bearing journal. The first web and second web each have a center of gravity (COG) offset from a plane defined by the crankshaft rotation axis and a longitudinal axis of the second crankpin. The COGs of each web can be on opposite sides of a plane defined by the crankshaft rotation axis and a longitudinal axis of the second crankpin. The COGs of each web can be substantially symmetrical relative to the plane.
