They all do - but you'll need the fork brace, and if using post 2001 forks you'll need the later type of brake calipers. You'll also have to feck around a bit with the brake lines.
These are the pale blue ones & will take your 1100GS brake calipers & ABS sensor (i you have one). As Neil said, though, you'll also need the notoriously crappy lower fork bridge.
Err, Jumping in here with a slightly off line question.
Thinking on the lines of swapping forks through the range of 1100's and 1150's and thinking about the various ways of lowering the GSs.
My question is; Would it be possible to firstly fit R of RT forks to a GS and secondly, is it possible to use the 19" front wheel in these shorter forks? IE is there space and would it be a direct fit?

Does this mean then that it is simlpy the shock absorber that makes the GS sit higher than the R/RTs. Or are the stanchions (chromed tubes) longer on the GS too?
What I'm getting at is; can I simply swap a GS front shock for either the R/RT front shock to lower the GS without causing other issues?
I was told by a dealer that the top fitting on the pure roadgoing bikes is fixed but on the gs and gsa itś flexible to allow for the greater suspension travel.
Just wondering, Neil, do you think it's the fork brace being different that gives the ability to fit the 19" wheel? I've not seen an R & a GS side by side, to check, but the 1150GS bridge has a good amount of clearance in between the forks. I'll bet that the 1100R bridge is much flatter...
