Thanks for the interest! Looking like I'll have time in the mill this coming weekend unless production schedule changes.
As he responded to you - the gsxr rotor bolts right up to the SV wheel, no issues. Should fit 1st gen also
Bump - I have a couple of them for what I'd call the normal rear (basically everything but 2017+ GSXR1000) and those are still $70. I have a few of the 2017+ GSXR1000 rotors as well now - $100 (had to buy brand new rotors from Suzuki in order to work on holding fixture & program).
