Yea they look fine to me... Lots of tread left man. All I'm seeing is some melted rubber chunks which is normal for the track from my limited experience. I could get 8 days or so out of my SC pros but thats on an SV.... I'm definately not expecting that from the new 600RR
I would be riding those tires for a while longer. Lots of tread left in them. You also don't have to worry about heat cycles like you would with a race tire. I would keep them in play and get your money's worth from them.
