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 It was swiftly superseded for 1952 by the more powerful R67/2, which was updated with full-width aluminium-alloy hubs and alloy wheel rims when these were introduced across the range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.

Frankfurt Motor Cycle Show in October 1951. This was the 594cc R68, readily distinguishable by its restyled valve covers that hinted at the engine's enhanced specification. The latter included bigger valves, needle-roller rocker bearings, high-performance camshaft and larger carburettors, all of which contributed to a maximum power output of 35bhp, which was good enough for a top speed in excess of 100mph. | Frankfurt Motor Cycle Show in October 1951.
