I had a Michelin radial on the rear of a bike once. It didn't last any longer than any other tire I've used except maybe the cheng shin I had to get once because I couldn't get a real tire. It was a real buggar to get on and off the rim because it was made really stiff to avoid the typical radial roll-under. I don't think they make motorcycle tires anymore.

Let's hope there's intelligent life somewhere in space 'cause it's buggar all down here. -- Monte Python
