I just bought a gsxr750 and had the dealer put on Q3 tires for track days (as I'm more familiar with the Q3s). So, I have two new Battlax Hypersport Tires - BT016. Rear is 180/55. Front is 120/70. Z ratings for speed. Tires have literally 2 miles on them (dealer did the check out ride on these tires before levering on the Q3s). $160 for both (which is over 30% off Revzilla price). I'm in Marietta, GA (East Cobb actually). Tires need to be picked up near there. Thanks!
