My first cbr had pirelli's , i thought they were amazing, and they were. but the price came into play. Bought a michelin pilot power rear and got hooked. As for track tires, i'm going with the michelin power race front and the rear i'm gonna go with the michelin power pure rear, maybe not, not sure. I also have a set of michelin slicks. I had initially brigdestone battlax's on my rc at barber. I should have swapped them but eh, what can you go. They just didn't grip like the michelin's im used too
