BMW motorbikes use Sachs clutches. That says everything, basically. After years of riding your machine, and thousands of miles, the inevitable gradual wear and tear means that your clutch will need some attention sooner or later. When the time comes, you should choose original parts from Sachs. For example, the original Sachs diaphragm springs for various BMW motorbikes. Manufactured from original materials, to original specifications. High-quality spring steel for reliable power transmission. Extremely smooth operation.
