| A '''Twin cylinder''' [[motorcycle]] is distinguished from other engines by having two driving [[piston]]s and [[connecting rod]]s to the engine's drive shaft. The cylinders operate with one piston at the top of a stroke while the other is at the bottom of a stroke whether in a [[two stroke]] or [[four stroke]] engine thus creating a engine balance. Twin cylinder motorcycles can have a single or dual [[exhaust system]]. It can be four stroke or two stroke in configuration. In some instances a two cylinder, two stroke can have 2 spark plugs with only one active.
