A '''V-twin engine''', often just '''V-twin''', is a two cylinder [[internal combustion engine]] where the cylinders are arranged in a [[V engine|V]] configuration. | |||

There is some ambiguity regarding what defines a V-twin. When the cylinders are arranged in a "V"-shaped pattern, it is generally accepted as being a [[V engine]]. However, some authors differentiate using "V-twin" to mean the classic V design of a shared [[crank pin]] for each pair of cylinders and "V-2" to indicate a crankshaft with a separate crank pin for each cylinder. This convention is not common, and applies only to two cylinder engines. For example, while most V8 engines use shared crank pins for cylinder pairs, they are not referred to as "V-octuplets". | There is some ambiguity regarding what defines a V-twin.
