I don't know what my lap times are, they weren't timed. I can't be that fast, I'm only hitting 128 in the back section. After two days at the track, it looks like the Powers have better than half the available tread depth remaining. I know I don't make gixxer 1000 power but it is an SV1000 rather than the 650.

I'm hoping to get to the point where I'm able to ride to the limits of the bike with the relatively inexpensive tires and then if I feel that I need to go faster, stepping up to a more capable tire. That method worked reasonably well for me with autocross, so for the time being, I'll stick with that plan. If street tires start to get spooky I'll take that as an indication that I'm either approaching their limits or doing something screwy that needs to change.

Of course part of this is an effort to keep costs down so that I can go more often.
