I've heard of lots of other people also running 150/60s on the rear, 110/70 front, 120/60 and 120/70
So far I've got 4K on my diablos, the rear is starting to develop a flat spot, but the front still looks and responds like a brand new tire. I expect 5-6K out of the rear and 7-8 out of the front. We'll see within the next thousand miles or so.
