Bridestone R10's are a great tire , and if you haven't done so already , raise your forks about 10mm on the ZX6.
Is that specific to the 2013 ZX6R? Just wondering because my steering geometry and forks are slightly different then the 2009-12 ...I have heard it is popular to raise the newer GSXR's and Ohlins makes taller fork caps so you do it, but I havent heard of it being done one ZX6R's.
I might have a Ohlins NIX 30mm kit in by the time the track day comes
