BMW Motorrad presents the M Endurance chain. Lubricating your chain was yesterday. Maintenance-free like the shaft drive for the first time.

  Munich. For more than 90 years, the maintenance-free,  environmentally friendly and comfortable shaft drive has been one of  BMW Motorrad's immovable technical cornerstones. With the M Endurance  chain, BMW Motorrad now offers a maintenance-free chain with  comparable characteristics for the first time.

Like previous X-ring chains, the M Endurance chain has a resident  permanent lubricant filling between the rollers and pins, enclosed by  X-rings. What is completely new, however, is that the previously  necessary additional lubricant addition for the rollers and thus the  familiar "chain lubrication" is no longer necessary, nor is  any re-tensioning required from time to time due to the usual wear.

This enormous gain in comfort was made possible by using a new  coating material for the rollers: tetrahedrally amorphous carbon  (ta-C), also known as industrial diamond. This coating is  characterized by extreme hardness and resistance and in this respect  it is placed between the well-known DLC coating (Diamond Like Carbon)  and pure diamond. In contrast to the metal surfaces used so far, the  coating with the ta-C industrial diamond does not wear off. At the  same time, this type of coating also offers a drastically reduced  friction coefficient.

Thanks to excellent dry lubrication properties and the elimination of  wear, the tetrahedral amorphous carbon coated rollers of the M  Endurance chain offer maintenance comfort equivalent to that of a  shaft drive motorcycle. This includes all the cleaning work that is  unavoidable with a conventional chain due to splashed lubricant.  Accordingly, the M Endurance chain also offers maximum environmental friendliness.

The M Endurance chain in 525 pitch is now available initially for the  two 4-cylinder models BMW S 1000 RR and S 1000 XR. The M Endurance  chain is available as accessory or directly from the factory as an  option. Further BMW Motorrad models are being prepared for this feature.
