In 1960, at the International Bicycle and Motorcycle Exhibition Show in Cologne, BMW presented the R 50 and 69 S models as a completely revised model range, and the R 27 model was presented for the first time to the public as a new release.
Like its predecessor, the R 27 model featured a full-swing chassis but with a new update. The engine was supported onto the frame by four rubber mounts that provided smooth-running characteristics and set benchmarks for single-cylinder engine constructions.
The R 27 models feature was presented as a floating engine and kept in place a 247cc single-cylinder engine with a power output of 18 hp at 7,400 rpm. With a curb weight of 162 kg (357 lbs), the bike was registered with a top speed of 130 kph (80 mph).
In the braking department, the model featured a 160 mm full hub drum unit both on the front and rear wheels.
Standard features that came with the bike included a single seat, wire-spoked wheels, an exhaust system with a large muffler, a large headlamp, and full fenders.
The production of the R 27 model was discontinued after 15,364 units were manufactured. BMW did not release any successor for the model until 1993 when a BMW single-cylinder bike rolled out of the manufacturing plant.
