I clean the chain today when I observed that there is a movement of the rear sprocket on my motorcycle, 2022 BMW S10000R. Is it normal that movement?
OK, please talk on my language! This is first time when I face such a problem. So, that movement of the rear sprocket is totally normal on BMW motorcycles. Is this what you say?It is normal to get the front to rear rock of the sprocket in the hub. I dont like it either, but there is not much can be done. The cushion rubber is not large enough and trying to make it larger and have compression strength would be a challenge.
Its really annoying...OK, please talk on my language! This is first time when I face such a problem. So, that movement of the rear sprocket is totally normal on BMW motorcycles. Is this what you say?
If you drive it with this play you will understand.Why is it annoying? It is designed to do so. They do wear out but easily replaced and very cheap.
I love the rubber donuts in the HP version wheels from 2013 to 2019 K46. Even other carbon wheel manufactures use this rubber donut drive method.If you drive it with this play you will understand.
They are poorly designed when they wear every 1000km. They are designed to absorb forces not to have a play.
It's easy to replace and really expensive for a piece of rubber.
Your 2018 wont have this issue if you have forged wheels. Just turn the donuts in the forged wheels and this will resolve the issue 3 times of the donuts life.It's an old problem, I never had it on my GenII Busa but the ZZR1100 before that was a shocker. I shimmed the cush drive with some old thick leather pieces and the problem went away. I think I have the problem on my 2018 rr, I'll check it out when it's on the stand. Fixing it, shimming it, certainly makes for a more enjoyable gear transition.
