The first 1500 miles were great for my RS2's. After 1500 miles, my front started handling poorly and at 2000 miles. It was so bad, I thought there was something wrong with my bike. It was by far the biggest POS front tire I've ever run. I NEVER wear out my fronts, but usually replace them when the rear wears out(+/-3000 miles). I've run PR2's, Angels, Z8's, Powers, Roadsmarts, Contimotions, and Road Attack 2's. Replaced it with a Power and all's well with the universe now!
The rear still looks great and still handles and grips exceptionally.
