BMW Motorrad presents the M Endurance chain - Lubricating your chain was yesterday. Maintenance-free like shaft drive for the first time.
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 S1000RR and S1000XR. Further BMW Motorrad models are being prepared for this feature.
X-ring drive chain:
-Maintenance-free Drive Chain:
--No lubrication needed.
--Minimal chain stretching occurs which minimalizes chain slack adjustments.
-Diamond Like Carbon coating material:
--DLC-coated rollers and bushings
-Permanently holds lubrication between the rollers and pins.
-DLC coated rollers and bushings:
--Coating material is Tetrahedral Amorphous Carbon (ta-C) which is also known as industrial diamond.
--This coating material is characterized by extreme hardness/resistance and in this respect, it is placed between the well-known DLC coating and pure diamond rating.
--In contrast to the metal surfaces used in the drive chain industry thus far, the ta-C coating does not wear off.
--This ta-C coating provides excellent dry lubrication properties which drastically reduces friction and can provide approximately 1% more power to the rear wheel.
--Due to chain cleaning and lubrication no longer needed, additional chemicals for normally required drive chain maintenance will not be released into the environment.
