Thanks for a great walkthrough. I am changing the chain and sprockets myself today, and wanted to check YT to see if there was a video of it. The video was very helpful 👍🏻
Thanks for the video. I watch alot of videos on the rear sprocket on the bmw bikes alot of people put the liped side of the rear sprocket facing out... on my s1000xr i also replaced my rear sprocket and found that with the liped side facings out there was a different measurement compered to the OEM sprocket so Thanks for confirming that the liped side faces in to the hub this,gave,me the same measurement as the OEM sprocket.
Sorry about the bolt. Just reading a forum prior to watching your video that THAT particular bolt is listed as single use. Some fella's opted to torque to below spec and use some blue threadlock. Others bought several spare bolts from BMW. And some bought replacement bolts from suppliers M20x1.5 30mm of much stronger grade than the chinese supplied cheese strength bolt BMW has given us. Thanks for the video, I'll be using it as I have decided to replace my front sprocket with a rubber fronted 16T. This will give a more flexible final ratio for the 850's thin bottom end torque to work with.
Sorry, I may have misspoke. I believe the bolt you showed to torque to 200 NM was the one they were referring to. Still, seeing what happened to you, it may be wise to use a new part for that sprocket bolt. Annoying that BMW has opted for bolts of cheese strength.
How did the front sprocket bolt break? Was there some kind of crud in the threads inside? What caused enough resistance that it broke ... or was it a problem with the torque wrench? 🙂
Why not show how to really show the wear such as by pulling the chain from the center rear of the sprocket or with the chain off comparing how much the old chain sages side ways compared to new one
BMW service manual recommend you also replace the "chain failure protection", seems overkill though
Great video, thanks for this. Will try do it myself as well now. Allthough can these torque settings be found online somewhere? thx

Never heard of a single use front sprocket retaining bolt before, thanks for the info.

Probably the torque wrench. I don’t think its very accurate

To be fair, that chain’s in better nick than I am.
