Another S1000RR Shock Question

[oldninjaron]

Hi
Carried out this mod using early 2009 shock (bronze fork) but instead of drilling both mounts to 12mm, I followed another method spotted elsewhere which retains 10mm bolts using custom bearing sleeves, OD 12mm ID 10MM, fitted to Fazer mount points.  150mm dog bones fitted to return rear to OEM height.  I fitted 110NM Ktech spring to shock, set Compression adjusters to BMW "Comfort" positions and Rebound to 7, so far.  At same time fitted R6 5EB forks, resprung also.  Bike handles great just harsh over sharp bumps.  Came back after latest run found what feels like top mount worn, lifted rear found a lot of play, I now have correct spacers for top mount to fit but it may well be BMW top shock mount may be extremely worn - if necessary how do you remove the top bushes, any help would be much appreciated?

Checked rear end again and found that able to raise, on centre stand, rear end a fair bit, spotted top mount moving up and down.  Fitted correct shims for this mod now play considerably less but some still present.  May have to drill bushing to 12mm and fit suitable bolt to correct any further play perhaps introduced play by using bushes to continue to use 10mm bolt?


Further to above, "Rider" sag before above 35mm now very close to 30mm, just shows how much play there was, just means I could back off shock preload to get a match with sag on front end of 35mm for a balance.  I have plenty of nose down attitude as R6 5EB forks are shorter than OEM Fazer - dog bones 150mm to bring rear end down to OEM, S1000RR shock longer than OEM.

Hi,
how did you manage to get the bushes out of the top end of the shock?I am just about to fit the shock to my bike. I bought lowering kit by 25mm, so it should keep the rear end about the stock hight.
I will be fitting the early R1 4xv front forks, so will see what the difference will be.
Anyway, I saw some kind of kit to higher the front end just for this purpose.

In the end took a much closer look at the rear end.  I did not remove the bushes on BM shock, I fitted suitable spacers at top mount along with bushings which allowed retention of 10mm top bolt - no drilling top or bottom of shock.


Once all fitted all play at shock top removed thats when I found play at the front mount where connected to frame, once this sorted all good.


Rear end is set at OEM, height front lower as early R6 front forks fitted.  Forks and Shock resprung to suit me, front end a bit harsh over sharp bumps, ideally needs revalving, but this bike handles a lot better and is very accurate through the twisties.  It compares very much like my previous bike GSXR1000 which was resprung/revalved - pretty happy.


Not sure how your USD forks compare lengthwise to my RWUP r6 forks - info on this site somewhere - but if it is anything like mine I would ride the bike with lower front end - you might prefer it.

Finaly I have managed to fit the S1000RR shock yesterday evening and used lowering dog bone kit by 25mm.However, I read some information this morning that the early s1000rr shock is longer than the newer one. The newer ones lower fork is in silver colour and I have got the same - the newer one.Now I am little bit confused, whether I should swap the lowering dog bones back to standard dog bones to keep the rear hight basically in the same level or not.

Hi


The earlier shock is the longer version.  I have one of those fitted.

I have 150mm dog bones fitted which brings rear end back to stock height to compensate for longer shock - lower is bronze.  I suspect as your shock is the shorter version - you may be able to get away with stock dog bones.  Did you compare shock lengths between stock shock and BM before fitting?

[kralik]

I did not measure it but I found an information that the bmw shock with silver bottom, the one I have, is longer by 4mm than fazer shock, which is good. Hence I swapped the standard dog bones back.Now I have to wait till I could ride it again.
Cannot wait🤩
