Looks like Zorro has been at your tyre! 
Got 2ct’s on my gsxr600k5 done plenty of road riding and trackdays, 10,000 miles on two sets, I’ve never had an issue with these, great grip, no puntures.
Mrs Gsxr has them on her ER6N again no issues after 3000 miles.
Got diablo corsa’s on my 1000, great when warmed up a bit slippy when cold, wear rate is ok.
