You're pretty buggered if you want a straight swap. There is nothing out there as available as GSXR stuff problem is half of "factory streetfighter" (BS!) bikes have their nuts cut in the engine and handling department meaning there is no point, only one is maybe the 'prilla tuono. But this is not cheap for parts.

Both 650 and thou have same options for swap, pointy is same stem as thou. If you are swapping forks anyway what does fork diameter on original matter. You will not fit any USD into 46mm yokes.

I think comfort kit is big con, I just beef up GSXR yoke with some ally plates and bolt risers on. Works well on mine and others.



For my money I would buy some late model (K4>) GSXR 600/750 parts which have right spring rate for you to start with.
