What other BMW singles were manufactured after World War II?
In all, BMW produced six shaft-drive thumpers after the war, all with similar 250cc OHV engines. The first, in 1948, was a copy of the pre-war R23 and was designated the R24 (engine numbers 200 009 – 212 007). It was unique in that it had no rear suspension—the only postwar BMW so unequipped (see photos below). Thereafter, from 1950 to 1956, came bikes with rear plungers and front telescopics, all having exposed shaft drives and “bell-bottom” front fender skirts. These were the R25 (engine numbers 220 001 – 243 400), the R25/2 (engine numbers 245 001 – 283 650), and the R25/3 (engine numbers 284 001 – 331 705).
