Got it - i have a 2012R. I did a little hunting around and it appears that all D675R's (2011R+) have the same fork C-C spacing, but you should confirm.
Measuring mine: the forks are 200mm c-c
. In case you're interested, the R lower fork diameter is 54mm, upper is 50mm. I included a picture of some of my measurement notes to jog my memory in case you have Q's. Let me know if there's anything else I can help with.
Try PM'ing the OP on this thread: link
. It looks like he did a swap from a gen 1 to gen 3 front-end and may know. You could also call Attack Performance - they would definitely know if all the R's are the same.
