I installed the PL690 on my F658. I think it is not as solid as it should be. It shakes easily.When you are taking a curve and lean the bike, if the surface is a little rough, it shakes a lot. If vibration of the bike matches the resonance frequency of the system, depending on the sizes of the cases, weight etc., you don't feel the rear and anymore. Besides you have to have the top case mount as well to install the side bars. They did not have to design it that way but I guess it is a way of guaranteeing higher sale rates :(. I am looking into modifying the connection to reduce the shaking. If I cannot, I will be getting rid of them.

The Givi bags are great, I've been very impressed with them over the many years and bikes I've used them on.

The Givi mounts are garbage. Flat out. I was riding a pretty mile off-road trail on my F650GS years ago with my E52 on the rack. There was nothing inside but a sleeping bag and air pad (not a lot of weight). At one point things felt a little funny and when I stopped I saw that the E52 had migrated from the TOP of the bike to the REAR, rotating down so the bottom was facing my tail light.

This was the cause:


As I said, I really like the cases and use them to this day, but I WILL NOT buy Givi mounting brackets. SW-Motech brackets are MUCH BETTER and have secured my cases over seriously rough terrain where I was really worried about whether they'd hold up. They've held far beyond the weight limits in the side cases (not over rough terrain) and come through like a champ.

The only problem I've had has been that the three quarter-turn bolts that hold the givi adapter plate on lose their tension after a while. I just removed them and worked up a more permanent attachment with M4 bolts, lock washers, and a couple of hose clamps for good measure. Ghetto? Maybe, but functional and invisible when I have the top case on.

Now I have a top plate coming from Motooverland which should open up my mounting options considerably (I generally don't use the top case when riding solo on a trip, I use a dry-bag strapped on top and the side cases if necessary).
