I'm not tire expert (hopefully someone reading this is and can help) but, if ALL the tires make this sound and vibration, it it the TIRES? I would think that if every tire you put on the bike has the same problem that it's NOT the tires. Somebody please straighten me out. I never felt this on any other bike (I haven't been on ALL of them - YET!) I can't imagine what causes it to happen on this bike and not others, but it's hard to belive ALL tires would do it. My ZR-7 had Dunlop D208s (

I'm not saying I don't believe you guys - I just don't understand. Can you help me out? Thanks.
