BMW M Endurance Chain Maintenance

How to maintain the BMW M Endurance Chain

Since late 2020-onward BMW S 1000 motorcycles (e.g. the latest BMW S 1000 RR)— and maybe others in the future — are fitted with an M Endurance chain, we need to clarify exactly what maintenance is required.

The BMW M Endurance chain is marketed as a “maintenance-free, like the shaft drive” on many BMW motorcycles.

But similar to a shaft drive, the M Endurance chain still needs some maintenance.

BMW M Endurance Chain — Low Maintenance, not Maintenance Free

BMW themselves refer to the M Endurance chain as a “low-maintenance” chain in their own motorcycle manuals.

See the manual for the 2021+ BMW S 1000 R for example:

BMW M Endurance Chain is the Low Maintenance Chain
BMW calls the M Endurance Chain the “low-maintenance chain” in the manual for the S 1000 R.

In traditional X-ring chains (the chains on most modern motorcycles), there’s a permanent lubricant filling between the rollers and the pins, enclosed by X-rings.

When you lubricate a normal chain, you’re lubricating the contact surface between the metal rollers and the sprockets.

You don’t have to do this regular maintenance on an M Endurance chain. Nor do you have to do the regular re-tensioning.

On most motorcycles, you have to clean, lube, and re-tension the chain every 300-1000 km (200-600 miles). You should do this more often if you ride in the dirt, sand, through water, or in the rain.

For the BMW M Endurance Chain, the requirements are much less stringent. You still have to lubricate the M Endurance Chain — but you lubricate an M Endurance Chain, at minimum, as part of your annual service.

The manual for the BMW M Endurance chain-fitted motorcycles says (edited for clarity):

  • The low-maintenance drive chain is cleaned and lubricated as part of the annual service.
  • For optimum durability, the low-maintenance chain can also be lubricated at intervals by application of a chain lubricant suitable for low-maintenance chains.
  • If riding involves above-average wear and tear due to exposure to salt or dust and dirt, carry out lubrication at correspondingly more frequent intervals.

So to lubricate the BMW M Endurance chain annually (or more frequently, if you ride through sand and dirt), per the manuals:

  • Clean the drive chain with a suitable cleaning product, dry it and apply chain lubricant.
  • To prolong chain life, BMW Motorrad recommends the use of BMW Motorrad chain lubricant or “Chain spray, O-ring compatible”.

This is from the manual for the Jan 2021 BMW S 1000 R.

So in summary

  1. You need to clean and lubricate your M Endurance chain as part of your annual service
  2. If you ride in harsh conditions (salt, dust, dirt), then clean and lubricate your M Endurance chain more often.
