In January 1955, BMW presented the BMW R 50 and the BMW R 69 as the first two models with full-swing chassis. In April 1956, the 600 Series tourer model, BMW R 60, rounded off the BMW range when it replaced the BMW R 67 sidecar combination model. Since the engines were virtually unchanged compared with the predecessors, the power unit corresponded to the BMW R 67/3 which provided sufficient traction even for use in sidecar combinations with 28 hp and an enormous torque. The key innovation here was also the full-swing chassis.
