My buddy just put a set on his bike. I am really waiting to see how they perform. They are hard, inexpensive and look like dual sport rubbers IMO. But WFT, not my bike, not my $$$.

Tried a rear one last year, my parts guy got some in and wanted so me feedback on em so sold me one for $50 to try it out. Very hard, slow to heat, didnt stick all that well heated, very flat felt slippery turning. I only gave them about 3 or 400 miles to be honest, i disliked them that much i took it off a couple days later.

I think they're ok for people who ride at a casual pace, but not hard riders. They're definitely a bit flatter in the middle than most other tires. I think you can do better.
