Just a heads up on some of the luggage rack that are out there.
Here is a OEM that broke all on it's on. The reason for it's failure is
do to the fact that the distance between the mounts and where it attaches to your bike. The distance on the luggage rack is set or fixed with it's on tolerance and where it attaches has it's on also. But you have the finder,spacers,stays,sissy bar mount and the sissy bar. So with this type of rack you should shim it. this one had a lest .100 gap.
