When BMW launched the new swing-arm models BMW R 50 and BMW R 69 in 1955, the BMW R 67/3 (successor model to the BMW R 67/2) was the only plunger suspension model left in the BMW range. Compared with its predecessor, there were hardly any modifications but the BMW R 67/3 was only supplied as a sidecar combination from the factory. All the government agencies and associations remained true to the BMW R 67 Series. When the R 67/3 was discontinued in 1956, BMW departed from the plunger-suspension chassis which had defined the profile of BMW motorcycles since 1938.
