The BMW R75 was an incredibly large, heavy duty bike. This was one of many German motorcycles specifically built to operate with a sidecar. Consequently, the sidecar is equipped with racks to carry weaponry like machine guns or mortars, essentially turning the entire thing into a mobile weapons station. Primarily, these BMW motorcycles were used in Kradschutzen units (mobile motorcycle forces designated within Panzer divisions). In addition, they were occasionally used by paratroopers since they could be stowed in the cargo hold of Junkers 52 Transports to be dropped later. Today, they are considered worthy war relics among collectors as desirable, authentic pieces of history.
