  Introduction to the BMW twins
  
  Although BMW’s use of a shaft-drive motorcycle with a horizontally opposed twin -cylinder engine dates back to 1 923, when the R32 model appeared. the machines described in this Manual were first introduced in 1969 to replace the high-quality R50/60/69S Earles Fork models which had been on sale since 1955, but were thought to be too unconventional in appearance to remain successful.
  
  The major changes to the engine of the new machines were the substitution of a plain-bearing crankshaft for the previous ball-and-roller bearing component, the fitting of an electric starter and the use of a crankshaft-mounted alternator instead of the previous gear-driven dynamo. The camshaft, previously gear-driven above the crankshaft, was now mounted under the crank, driven by chain and used to drive the oil pump at its rear end; the repositioning of the camshaft had the effect of raising the cylinders for increased cornering clearance.
  
  The most obvious changes were to the cycle parts, where a new frame gave a conventional appearance to the rear suspension, and where BMW reverted to the use of the telescopic fork; they had first used this type of front suspension in 1935 but had abandoned it in
  
  favour of Earles forks in 1955. The new suspension components were softly-sprung and gave a smooth, comfortable ride, which has become
  
  one of the marque’s most popular features.
  
  Although the machines described in this Manual have remained basically unchanged, especially by comparison with the products of
  
  the Japanese, most of their components have been modified in various degrees throughout their production life. The need to keep pace with the competition has resulted in larger-capacity engines with greatly increased power outputs and in the appearance of features such as five-speed gearboxes, disc brakes, cast alloy wheels and a much greater diversity of model types. Most of these changes can be seen by reference to the Specifications Section and/or introduction to each chapter.
  
  Note however that as BMW have made it a policy to offer a wide range of equipment as optional extras, with the components fitted as standard to the more expensive models being available for the basic versions. and to keep all components interchangeable where possible, many machines may be found to differ considerably from the specifications given; these refer at all times to the machines in their standard, original, form with likely variations noted where possible. For example, it is quite possible for a basic model of one year to have twin front discs and alloy wheels when it is listed as being equipped with a single disc and wire-spoked wheels, or for it to be fitted with modified components which are listed for later models.
  
  A complete list of the models covered is given below. For reference, to assist the owner in identifying his or her machine the approximate dates of import are also given; note that these may not necessarily coincide with the actual date of sale. Unless specifically mentioned in the text, the later 1000 cc model information will be as shown for the Details of the 1986 on models are given in Chapter 10.
