after reading about this mod, I have replaced my original shock with a S1000RR '12 with 4000 km.
The shock works very good (everything works better than the original), the only proble is that with the shock fully preloaded I have a statit sag of 27 mm (against a reccomended 10-15) and a rider sag of 55 (against a reccomended 30-40). My weight is 90 kg
This make me thinking that the spring rigidity is correct, but the spring is too short, it'd be 10-15 mm longer.
What you think? Could I resolv with a 10-15 mm spacer under the spring?
ps sorry for my bad english...
Does your shock have the silver or bronze coloured shock fork. The silver one allow adjustement of the sag to 20mm the bronze one only allow adjustement of the sag to 27mm.
I did fit a 10 mm spacer to my silver forked one to allow more adjustment, but found that adjusting the sag to 15mm made it hop over bumps and set it back to 20mm. I weigh about 87Kg.

Do you have the dimensions and/or a picture of the one you made up? I was thinking of doing the same.
Re: BMW S1000RR shock conversion question - NorthWestern - 16-09-14
No pics I'm afraid. It was simply a "hat" type spacer. Basically measure the std bush but with a 2mm thick rim. This is in two parts (both identical), one for each side. I think the standard one is also in two parts.
Thats about all I remember really...

The shock is a 2012 with silver fork; at last I have used a spring from a R6 shock with a 10 mm spacer, and the shock works great with my weight (95 kg dressed). In this configuration I have obtained a static sag of 15 mm and a rider sag of 35, but I felt the bike too hard; actually I have reduced the preload of 6 mm, with a rider sag of 41 mm, and I feel much more confidence and comfort.
The rebound damping is set to 5, I switch the LS compression damping between 2 and 3 depending on the road; the HS compression damping is 4 as standard, I have no idea how to set this one
Re: BMW S1000RR shock conversion question - CatalinU - 19-06-19
So wich one should I choose? The one with the silver fork or the bronze fork?
Re: BMW S1000RR shock conversion question - PieEater - 19-06-19
Sheesh in 4 and a half years I'd be surprised if you could tell the difference :eek

I’ve got the bronze one. It’s epic
Re: BMW S1000RR shock conversion question - CatalinU - 23-11-19
Anyone knows what bolt should i look for to reuse with the BMW shock?
Re: BMW S1000RR shock conversion question - unfazed - 23-11-19
A 12mm bolt with the shoulder 41.5mm long, you can cut it to clear the dog bones and leave a few mm more than the nut..Important bit is the 41.5mm shoulder
Re: BMW S1000RR shock conversion question - CatalinU - 24-11-19
OK, perfect, thanks very much.

Any tip on how to adjust the shock? I am 100kg and riding solo. Any start point will help
Re: BMW S1000RR shock conversion question - unfazed - 28-11-19
Is it the one with bronze bottom fork or the silver bottom fork?
Re: BMW S1000RR shock conversion question - NorthWestern - 28-11-19
Catalin, a new spring would be the first thing to get.

A spring for the BMW shock?
Re: BMW S1000RR shock conversion question - unfazed - 01-12-19
Set the rear preload 15 to 20mm, be careful not to wind the adjuster off the threads as it will damage them.
Set all damping adjusters to 4.
I weigh 85kg and my wife about 55kg which is 40kg more than your weight and have toured with that setting.
After 20000km I changed the damping to 5 all round and never had to touched the preload in that time.

Ok, thanks for the feedback, will be doing that soon it gets to me. Thank you

I was lookin over your advices. Why didn't you use a 12 mm nut for the 12 mm bolt?
Re: BMW S1000RR shock conversion question - unfazed - 13-01-20
I didnt have a suitable self locking nut available at the time.
