Yeah man I know! But its true, they are supposed to be the lightest dual compound tire on the market right now. I went from the Dunlop Sportmax GP-A's and it was night in day in the weight. I had to re-adjust my suspension to deal with the difference. I still have to do some fine tuning on that end! But they are awesome, I just have to do a little riding to get the wax off and then I will probably be taking it to VIR this weekend to make a few runs and see how they do. I have another set of wheels that I run full track tires on when I go, but I am tempted to run a few laps on these just to see how far I can push them compared to the almost full slicks I run there.
And for tire size I am running a 190/55, and it has made a nice difference in handling I must say. Although for me being 5'6" and already having to balance on tippy toes, it took some getting used to for street riding lol
