I've run Conti Motions front and rear, several sets, on my VFR800. I get 4,400-5,000 miles on the rear. I mean, to where the steel cord is showing. I decided on the last pair to try and run the front tire through two rears, trying to get 9,000-10,000 out of it. I would now say that was not good. The front, at about 7,500 miles, developed a noticeable crown with flat sides. This caused handling quirks that I did not care for.
