Grüezi Ben! I am really surprised he would put a radial on the bike with a normal-ply tire, that is kind of dangerous I would think!! I have an Avon Venom front and Dunlop K555 on the rear, but will get the Avon rear when I replace the Dunlop (very soon) I wish we did have radial tires for our bikes, because you are right, they make a big difference in handling! Till then, I'll use the Avons I think.
