Hiya Tatran and I fear that they are all different!! I had a PCIII for a 2005 R1 and asked if I could fit it to my 2008 R1 and they (Dynojet) answered very quickly and told me no way Jose, so I would not think that you can swap anything at all.....unless of course that is just because they want to sell more units?? Cheers Simon
