Rare, beautiful condition and accurately restored. A museum example to collect or ride. Rarely does a bike like this come up for sale.The R51/3 was introduced in 1951 for a production run of four years.As was often the case with these bikes, BMW built the R51/3 with many part variations as they incorporated changes, i.e., the R51/3 had at least three different air filters. Early R51/3s like mine had a smallish rare black steel filter with wire mesh while later models had a larger filter that carried over into subsequent model years.A few of the many accurate restoration details: The metal fork tubes, half hub brakes, properly painted two-tone steel rims, tires, painted small air cleaner, petcock, carburetors, saddle, removable pinion saddle, new steel fenders - no putty anywhere, official hand-painted pinstripes, complete tool kit, swallowtail exhaust, handlebar, new correct wiring harness, headlight assembly, Veigel speedo, and taillight. Also included are the very rare owners manual, service manual and parts manual.
