It's called The Beer Engine. The Hogs Back Brewery in Tongham, Surrey, UK commissioned this custom motorcycle. As you can see, the sidecar is a beer keg, spigot and all. The gear shift lever is a beer engine pull. The owners use the motorcycle to draw the attention of crowds at festivals and other public events.
