German manufacturer BMW Motorrad has shown off an innovative chain that could considerably change the life of many bikers. Its new M Endurance chain requires less maintenance and no lubricant thanks to a new coating material.
The first two 4-cylinder models BMW S 1000 RR and S 1000 XR already offer this innovation as an option, and it will soon be made available to further models.
This new M Endurance chain gets rid of the need for chain lubricant and tension adjustments on its motorcycles, because it's made of etrahedrally amorphous carbon (ta-C), better known as industrial diamond. The substance is hard and resistant, eliminates friction, and therefore doesn't wear out.
The BMW press release highlights the maintenance-free aspect of this new material, and therefore its green properties. It eliminates "cleaning work that is unavoidable with a conventional chain due to splashed lubricant. Accordingly, the M Endurance chain also offers maximum environmental friendliness."
