I have run Commander II's on my Virago, and Harley, and put myself into some pretty stupid situations in the rain with them, and they have stuck it no problem, even when low enough in corner to expect the inevitable slide out, but never happened, they have been great on those bikes. Right now i'm trying out the Pirelli Night Dragons, on dry pavement, I would swear these things are coated in gorilla glue, The grab was fantastic, been caught in the rain a few times, and I have found that you go gentle on the throttle, or the back end is going to spin up. I don't think it is totally the fault of the tire, this thing is dropping enough torque that it is pretty easy to break a tire loose even on dry, (it is great watching peoples faces drop when you do that, not so good on tire life though)
