bosjt wroteA cantilevered load like your bike creates completely different loading conditions than a trailer on the ball. The dynamic load cases stress the structure much more so than with a normal trailer. If the CG is about the same as the 11.8" measurement from the manual, then you'd be 76% over the rated load for the hitch receiver [290/165=1.76]. Do more research with the LLM of your choice, but to be generous this is a bad idea.I fixed a typo above in my math... the combined bike and rack weight is 290lb not 390lb and I'll have to measure but its center of weight is probably 16" from the car which is similar to the 11.8" measurement BMW gives from the ball (if the ball could be present).
I think when you tow a big load with an 800lb tongue weight, that weight is right at the ball, which is 5" from the hitch let's say. Or maybe the ball is further out for a big load like that?
In my case the tongue weight is only 290lb, but its more like 16-18" away from the hitch... I just hope they didn't weld their factory hitch to the bar in a dumb way where it has no twisting strength. By comparison the Curt class III hitch is really beefy for resisting bending and it fastends right to the factory side rails with 4 big bolts.
At this point I can only hope or I will have ordered a big expensive car that requires me to find a way to cover a trailer outside in New England :-(
Curious best way to get the word out as a FS.

On FB find, join and post in appropriate groups (probably the general BMW groups, and something for X5). Post an ad in Marketplace and link it to those groups.
Craigslist used to be a place but is dead here; maybe still useful where you are.
If you’re a BMW CCA member, try their ads too.
