Having concentrated on refining what were essentially pre-war designs during the early post-WW2 years, [[BMW|BMW]] was ready with a new model for 1951. Designated [[BMW R51/3|BMW R51/3]], the newcomer boasted a totally redesigned, single-cam engine that went into the existing cycle parts. Also new for '51 was BMW's first 600cc model of the post-war era, the R67. Of relatively modest power output, the R67 was intended for sidecar pulling duty and was a far cry from the R66 super-sports roadster of pre-war days. It was swiftly superseded for 1952 by the more powerful R67/2, which was updated with full-width aluminium-alloy hubs and alloy wheel rims when these were introduced across the range for 1953. | Having concentrated on refining what were essentially pre-war designs during the early post-WW2 years, [[BMW|BMW]] was ready with a new model for 1951.
