So have done a bit of research and found that 99-07 GSXR-1300 Hayabusa and 03-04 GSXR-1000 have an Eye to Eye length that will fit on the FZ09. Only problem I can find is the busa shock has around an 800 pound spring rate and the gsxr 1000 shock has a 480 pound spring rate. The FZ has a 540? pound spring rate. Can I take the spring off the FZ and put it on either GSXR shock mentioned above or will it not fit?
