BMW Motorrad introduces maintenance free chain

- New maintenance free chain introduced 

- Doesn’t need lubrication 

- Available for S1000RR, S1000XR 

BMW Motorrad has just introduced a new maintenance free chain. The company claims that this M Endurance chain doesn’t need any kind of lubrication.  

The German brand says that this chain has permanent lubricant filling between the rollers and pins enclosed by X-rings. So there’s no need of regular chain lubrication. In fact, there’s no need of re-tensioning required due to normal usage wear.  

The company says that this was achieved by 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. 

Currently, this chain is being offered as an accessory in motorcycles like the S1000RR and the S1000XR. But we can expect the brand to use this as standard equipment in the future models.
