Can you use a tubeless radial motorcycle tire on a tube type rim?

According to Dunlop's site, "With a tube inserted, a tubeless tire may be fitted to a tube-type wheel." They offer one warning though: "Do not fit tubes in radial motorcycle tires, nor fit radials on rims requiring tubes, unless the tubes bear matching size and radial (R) markings."

So, as long as the tube is marked for radial use, you shouldn't have any problems running a tubeless radial tire with it.

The same SHOULD apply to Bias ply tired, but I can no confirm that.
