hi,i had a zzr600 last year,and my discs look the same as the discs you have,they were also cracked around the drill holes,but they still pasted the mot,i have a set of kr1s discs for sale if you want to buy them,they are black in the middle,they are new,but not genuine kawasaki,i am going to restore my own discs,so will not be using them,email me if you want them,thanks brian
Been looking at alternative front brake discs and apart from EBC, are there any other decent aftermarket discs out there ?
Has anyone bought some and put a few thousand miles on them with no issues ?
