Engine balancing was once considered a luxury reserved for high-performance engines.

The complex mathematical side of balancing can be observed in the design principles of high-performance crankshafts, and the benefits can be seen in the increases in torque and power that these principles yield.

The truth is that all engine types benefit from well-balanced rotating and reciprocating components. Reducing the mass of weight, revolving off the centre axis reduces frictional loses, increases bearing life, increases power output, and reduces engine vibration.
