The label says it all... Couldn't believe my wife's new huffy beach cruiser bicycle rear rack has twice the weight capacity, lol.. I'll send her to the store for the beer runs! 🤣🤣

 

Funny!
Seriously though, I've had tour pack racks on y last two Ultra's since the fall of '99.
I think the small weight limit is more for the protection of the tour pack lid that the luggage.
(I use large, chromed or black washers (from Rocket-Moto) that fit between the feet of luggage rack and the tour pack lid) for added protection to the paint and the lid).
I have however, had TWO luggage rack rails to crack on my '00 Ultra so if you have an older Ultra '99 up, use a mirror and check the rails (under the tour pack) around the mounting holes for cracking/fracturing. You can manually try to move the tour pack to see if there's any movement and if you see a tour packing "vibrating" on a friends bike inform him immediately.
