I only have two point docking, so fitted this rack ($200- p/n 53011-98), of course if you want to remove it the sissy bar has to come off as well, but thats not a problem once you get where you are going

 

If you look at the OP, he has a 2011 model.
Harley does not make that 2 Point set up for the '09/Later models.
I think Harley did this because the 4 Point Docking for '08/earlier sticks out so far back.
So Harley made the set up for the Earlier year 2 point Docking station.
But, like I said, they don't fit with the newer models. (maybe that is why they are cheaper too)

 

I weigh 150 and could probably stand on it. It is a pretty strong setup.

 

I know he has a 2011 model but I thought if he is using a two point docking system then the rack I have used will work for him as it attaches directly to teh sissy bar!!!

 

Here's what they are talking about, but I doubt if it mounts just to around the bar does it?

If you notice, it will not fit '09 or later models.
It will not fit the OP's bike.

 

It does in fact just mount around the bars, I have fitted this very rack to my sissy bar, I know my RK is 2007 but I cannot see any reason why it should not fit any sissy bar that is the correct width, take a look at the Instruction Sheet and can see clearly how it attaches. I think mine took no more than 10 minutes to fit. However once fitted to sissy bar it should NOT be removed.

 

Since the rear tire and fender are wider on the '09s and newer, I am assuming the sissy bar is wider than your's too.
