These have seen maybe 2 hours total track time, Penguin Pro School (rained out in June) and 1/2 a track day. TONS of life left in them. My bike is set up for Michelins, these didn't work for me.
Front: 120/70ZR17
Rear: 180/55ZR17
Currently stored in black plastic bags in my basement - heated, but away from the furnace.
Paid $300, asking $200.
