I have an 09, came with bto21 battle, stuck resl good but toast at 5500k, wore the sides off them, left a ridge diwn the middle. Them ran a set of pirellies, much better, now on my second set of michelin road pilot ii's, 15,000k's. less sticky, cant lean as far, but thats ok. A set lasts a season now. i ride from the prairies to the rockies, to the appalachians and everything in between. The mich's have been the best. I hear the III's suck. B.
