V-twin engine 75° crank pin offset for the rest of the world. Generally, a two-cylinder engine with the cylinders arranged at any angle greater than zero degrees and less than 180 degrees may be classified as a V-twin, although an angle that approaches zero is not practical. Despite Ducati referring to its 90 degree twin cylinder engine as an "L-twin"—with the front cylinder nearly horizontal and the rear cylinder almost vertical, there is no technical distinction between V-twin and L-twin engines. Assuming correct counterweighting, a 90 degree V-twin will achieve perfect primary balance. However, the 90 degree layout will produce an uneven
Less-is-better effect of top-quality candy than a box containing those 24 pieces plus 16 lower-quality pieces. If a manufacturer has developed two versions of a product and wishes to know which will be more popular with consumers and should therefore be put on the market, presenting them jointly to the public will enable consumers to evaluate differences between them, while presenting them separately will better predict the consumer's actual experience of the product when and if it is actually put on sale.
