RE: 2016 R1200RS shaft issue - 2

Is that the gearbox end or the final drive end of the drive shaft? Looks to me like water got in there. Maybe a damaged rubber boot?
BTW greasing the splines does not appear to be a specified maintenance item anywhere that I can find. Only necessary when re assembling after a repair.Why does everyone seem to think it's necessary on a regular basis? Am I missing something?

It's not difficult to do and having a look in there to ensure that corrosion isn't running rife is a peace of mind thing. I might do mine again. I change rear bevel oil every engine oil change too. Low volume means it's not expensive. I only did my rear spline. I might look at doing the front too.

If anyone knows of a full photo or YouTube guide it'd be handy.

Or I could make one...

The cushion drive rubbers are good it was replaced once I'm not mistaken 40k service.

Yes there is free play on the universal joint and that's not good ..

it's final drive end of the drive shaft.. and the rubber boot is good..

you mean many previous cases as well on this issue..?

Well the BMW dealer here recommends/informed Minor service at every 10k and 20k Major service when we purchase a bike.
Minor being engine oil and filter change and Major being the rest like spark plugs , air filter, valve clearance and shaft inspections together with bevel oil change.
This is the scheduled maintenance we adhere here for those who does not have the knowledge or correct tools to do their own inspection or maintenance.

rgds,

This is not wear or condition I would expect to see on a bike with this low mileage and I will put it out there that if the bike was purchased 2nd hand then it could have had the original part robbed to repair another bike typically a GS and the worn item swapped from GS fitted in its place.
Check to see if there is an inline shock absorber built in to the shaft at the front end it takes the form of a tube over the front 1/3 of the shaft and if this is the case then it confirms my suspicions the the RS shaft has been replaced by a GS shaft because the shock absorber type was not fitted to the RS until 2017 model year. All pure speculation but worth checking.

My concern would be the condition of the male splines on the rear wheel drive end because the female portion is badly worn with chattering marks and no sign of grease so worth double checking.

Just an update .. got a free replacement from BMW for this issue...its all good now..

Thanks..guys,,

There I was sitting in the lounge at Brown's Motor Works having my 114K service. When the technician (AKA the BOY) ushered me to the
cone of silence, to inform me that I needed a new drive shaft not happy. All things considered no better get this news. Visually the drive shaft look fine
but the U-joints where very notchy.

If that's 114,000 miles I'd rate that as a job well done. Can they not just change the joints?

---

No. The joints and shaft come as one non-serviceable US$1200 part.

I'd be looking at a breaker's low mileage shaft and doing it myself....
