BMW Introduces “Maintenance-Free” M Endurance Chain

[Grumpy Goat]

See this article on Motorcycle.com.

What I want to know is why can't it be available on any [BMW] motorcycle that uses a 525 pitch chain? This is what the last paragraph of the Press Release says:

"The M Endurance chain in 525 pitch is now available initially for the two 4-cylinder models BMW S 1000 RR and S 1000 XR. The M Endurance chain is available as accessory or directly from the factory as an option. Further BMW Motorrad models are being prepared for this feature."

My S1000R uses a 525 pitch chain, so what is the difference if the sprockets see the same 525 pitch chain?
