I may as well add my $.02 here as well... I swapped out my stock tires at 3079 miles with Mitas E07 F&R. I wanted something fairly aggressive that I could get some decent mileage with. The rear E07 was fine, but I didn't like the feeling of the front at all. It made the bike feel like it was "falling off" of vertical when going into a turn. (Closest thing I can compare it to is notchy headstock bearings.) I ran those for about 1800 miles at which point I was given a set of TKC80's. The TKC's are great aside from the fact that the rear is pretty much gone after 1100 miles. I'd say I have about 30% of the tread left. I ride my Tiger pretty aggessively on the street, and the TKC's don't like that one bit. They handle great and stick like glue, but I don't want to be swapping tires out every 1500-2k miles. I am going to run the TKC for a bit longer, then put the E07 back on the rear. I'd say the E07 I have still has about 75% of the tread left at 1800 miles. I've read a lot on other forums about guys having good luck with a TKC 80 on the front and Mitas on the rear, so I'm going to give that a go.
