Seeking opinions or experiences. I just put some Givi hard bags on a 96, fourth gen. Had to buy the bolts to fasten the racks to the rear subframe. While getting them, I also picked up some rubber washers. Thought it would isolate them from vibration and absorb some of the inertial forces while riding. Would a hard, bolted mount deal with the forces better? Kind of an engineering question, or if anyone has had the same idea. They are on now, will take them for a test ride soon. (Tomorrow???!!!!!!) At a standstill, they have a little flex to them. If I push down hard, they will move an inch. (the bag, not the bolt) Thanks for sharing!
