I had searched awhile back on the radial/bias ply as I'll be in the market for some new tires soon. Here's what I found on Dunlop's faq site at http://www.dunlopmotorcycle.com/info-center/faq/
Can I change my tires from bias ply to radial or vice versa?
Bias and radial tires have significantly different dynamic properties. They deflect differently, create different cornering forces, have different damping characteristics, as well as other differences. In order for radial tires to be introduced into the two-wheel market, it was necessary to change certain characteristics of the motorcycle. The introduction of the radial tire led to such things as modified frames, wider wheels, new steering geometries and suspensions. Therefore, it is recommended that a motorcycle be used with the type of tire construction that it came with originally. If a change is to be made, then it should only be done if the motorcycle or tire manufacturer has approved the change. Above all, do not mix bias ply and radial tires on the same motorcycle unless it is with the approval of the motorcycle or tire manufacturer.

Liability because of fitment, the tire was used or because it's a radial tire?
They said they couldn't install it due to dry rot. Took the tire to a friend who sells tires as a living and he said they were crazy. Took the tire to another place who said they would put it on for me. Come to find out the tire was bad. When we started doing a hand inspection, the tire was as lumpy as a gravel road. The guy I spoke to said it looked like it had sat in the heat for a long period of time. He said he would be glad to take my money, but didn't think I would be happy with the ride of the tire. I guess the search continues.
