The set on my bike have been there for about 4.5K and I'll be replacing them with another set.. They're very good on the dry, so-so on the wet, they wear well, and they're (KLR world) CHEAP!!!
The set on my bike were installed last summer and I paid $94 for the set, shipped to my door!! Not sure what they're going for now, but I'm very happy with them.
On wet road, just don't ride crazy.. They're just like every tire was before silica rubber showed up on the market.. Not super sticky in the wet, but they do fine..
At 4.5K, I figure mine are a bit more than half worn, and I don't ride on worn out tires.. I'm guessing they'll need to be replaced at about 7.5K or so..
