The days of having to lubricate your motorcycle chain are over — at least if you own one of BMW’s sports bikes.

Yes, we’re talking a maintenance-free chain that doesn’t need any lube over its lifespan, and the secret ingredient is diamonds; more specifically tetrahedrally amorphous carbon (ta-C), which is also known as industrial diamond.

BMW Motorrad uses this extremely hard material to coat the rollers in its newly introduced M Endurance chain. The coating doesn’t wear off like the metal rollers used in traditional chains, and it rolls very smoothly too due to ta-C’s drastically reduced friction coefficient.

Thanks to its excellent dry lubrication properties and the elimination of wear, the ta-C coated rollers of the M Endurance chain offer the clean, maintenance-free convenience of a shaft drive motorcycle, says BMW Motorrad. It means you’ll never have to get your hands grubby cleaning the old oil from a chain.

BMW has offered shaft drive motorcycles — which also require no lubrication — for more than 90 years as one of its technical cornerstones, but this is the first time it’s offering a maintenance-free chain.

The M Endurance chain is available initially for the brand’s two four-cylinder models, the BMW S1000 RR superbike and the S 1000 XR adventure sport bike — either as an accessory or as a factory-fitted option for R4,029.

The feature will also soon be available for additional BMW motorcycles.
