The Conti SM's suck, the profile is all wrong. The Avon tractor tires just don't last long enough, even the puny DRZ cooked them in about 700 miles. Another 016 fan here, best tire I've had yet, very sticky.
Hm, I really like the ContiForce SMs. They've got great grip and good response. I don't know what's wrong about the profile? Only downside to them is that they wear out damn fast.
I can only compare them to the Pirelli Diablos that were on the bike previously though..
