Honestly, it depends on how much you ride with the traction aides off. I have a 2012 zx14r making 207rwhp, and my oem Metzler M5's lasted almost 7000 miles.
The only reason I replaced them was that the front was cupping badly on the right side. Went with Pirelli Angel GT's as there was a buy a rear, get a front free promotion. I hope to get 10K miles form these. BUT, I never ride with the ktrc off. Always 1 or 2.
Yes, people that ride a lot with it off, get under 3K miles from tires, but its fast enough on the street; why not let the traction control save your tires, and some money, and possibly your skin, lol.
