Built to the same exemplary standards as the Bavarian company’s famous flat-twins, the single-cylinder BMW first appears in 1925 as the 247 cc R39. Throughout the twenties and thirties singles are brought out in various capacities, ranging from 198 cc to 398 cc. For a number of years after the war Allied restrictions prevent German companies to produce machines of greater capacity than 250cc, so BMW’s first postwar model is a 247 cc single, the R24, brought out in 1948. In 1950 an improved model is presented, the R25. This is equipped with rear suspension, a refined engine and a welded tubular frame with sidecar mounts; the R24’s frame was bolted up. Engine dimensions are 68x 68 mm and the power output is 12 hp @ 5600 rpm. The bike weighs some 135 kg and can reach a top speed of almost 100 km/h. The machine on offer is an older restoration that has had one owner from 1969 till 2024. During these 55 years the R25 has been regularly used for a number of years, but has also had many years of storage in heated accommodations. The former owner was in his early twenties when he bought the Beem and has fond memories of holiday travels from The Netherlands to various places in Europe.

This well-kept R25 comes with luggage rack, rear view mirror, technical manual in Dutch, various copies of the BMW Mono Club magazine and current Dutch registration.
