BMW’s “maintenance-free” M Endurance chain put to the test - RevZilla
We put BMW's "no maintenance" M Endurance chain to the test and wear it out in just 12,000 miles.www.revzilla.com
TLDR:
“The claim is now going to be ‘low-maintenance chain’ and not ‘maintenance-free chain,’ since depending on the riding elements (dirt, salt exposure, etc.) you experience, it could cause stretch or wear to the non-DLC-coated elements on the chain which would then require cleaning/relubrication as well as slack adjustments.”
That’s the feedback I got from BMW’s Aftersales Marketing Specialist after I presented the results of Paul’s test. A far cry from the set-it-and-forget it promise that BMW originally made!
