I've been trying DOT race tires instead of slicks on my 1299 for track days. I'm not looking for all out performance but better value from my track tires. I've run Dunlop GPA med+ compound and found them to stick well and last about 1 1/2 days. Michelin Evo last about the same distance. I've used the Bridgestone slicks in the past and found they had better edge grip than the Pirelli. But I haven't tried the r10 or R11. The R11 are getting good reviews, but I haven't seen any comparisons. Has anyone tried the r11 and have experience with either the Dunlop or Michelin DOTs? How would you compare them?
