Re: Fork ID help
Hmmm....my best guess is those are from a 2009-2011 GSXR-1000 given the TiNi coating on the lower fork tubes. On the '12 1000 (and also the 2011-2018 600/750) they all have chromed lower fork tubes.
The 09-11 1000 didn't come with those Brembo calipers OEM either, it came with the Tokico monoblocks, but its easy enough to swap the calipers out as they are the same spacing....I have the same calipers on my K5 1000. BTW, I believe those are Ohlins 30mm NIX cartridges so the rebound would be at the top of 1 of the forks (should be the right leg) and comp at the top of the other, the red plug at the bottom is just a dummy/blank cover...but on the stock OEM internals that would be the preload adjuster, not rebound.
