BMW have announced a new chain which they claim never needs lubing or adjustment.
The BMW M Endurance chain uses an industrial diamond coating on the chain rollers for “extreme hardness and resistance.” It doesn’t wear off, BMW says, and it “drastically” reduces the friction coefficient where the roller interfaces with the sprocket teeth, and with the bushing surrounding the pin that holds the chain links together, which also gets the “tetrahedrally amorphous carbon (ta-C),” or industrial diamond coating.
There’s still a rubber X-ring seal between the inner and outer chain plates, presumably to keep road grit out, but since the M Endurance chain doesn’t need lube then dust shouldn’t adhere to the chain.
The BMW M Endurance chain comes at a price though, overseas the M Endurance chain is roughly the equivalent of $565NZ and at this stage is only being offered in 525 pitch as a replacement option for the BMW S1000RR and S1000XR models.
