BMW break-in procedure from R90/6 owner's manual: 

Vary engine speeds and loads in various gears without exceeding maximum specified speeds. Winding roads in hilly country are particularly suitable for braking-in the machine. On straight, flat foods, it is best to run the machine almost up to maximum permitted break-in speed, then allow the machine to cover the next section of road with the engine off load.
