TWIR: Maintenance-Free Chain Offered By BMW

It’s time again for TWIR – The Week in Review. This time it’s for the week of Aug. 23 through 29, although it does go back a little further this time because TWIR was missing in action last weekend.

TWIR is a compilation of national and regional news that didn’t receive a full post but warrants sharing. Here goes, with news from BMW and more:

No Mess, No Fuss With BMW Chain

BMW has sold maintenance-free shaft drive motorcycles for more than 90 years and now the German company is offering a no mess, no fuss “M Endurance” chain for chain-driven models.

BMW says that like other chains, it has permanent lubricant between the rollers and pins. Unlike others, no additional chain lube is necessary for the rollers. There also isn’t any need for periodic re-tensioning of the chain.

In a press release, BMW stated, “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.”

BMW is making the chain for its S 1000 RR and S 1000 XR models.
