I had figured out how to mount the E52 from my Concours on the Ninjette a couple of months ago, using a hacked up BMW rack, Givi mount plate, and the stock rear seat pan. Ended up looking like this:

I liked how it functioned, but wasn't happy with the fit and finish, and needed to add a bit more fore to aft stability (upgrade from the zip-ties holding the back of the rack onto the seatpan to a hose-clamp setup). Here's what I ended up with:

Here's the underside:

And with the case installed:

Damn 52 liter?

I almost got the 47, ended up with the 38 and I'm happy

Nice work on your case

Yeah, the 52 doesn't look nearly as freakishly huge on the Concours:

Yea for real, I passed on the 47 because it made my n1k look like a friggin goldwing :lol:

Nice setup. I have everything to do the same with my 30L Givi case. Any problems with keeping the seat secure? People have said to not trust the rear seat lock to hold the case in place. I did the same thing on my 03 636 and have had zero issues after many years of use.

Careful how much weight you put in there while riding. I heard the mounting system for the rear seat isn't all the strong if you have something pulling on it. But then again if that was the case anyone could just walk up to our bikes and rip of the seat, which I think is extremely hard. I know the instruction booklet for the monolock a says max 8lbs but I carried like 35 yesterday leaving harbor freight like this. http://i1157.photobucket.com/albums/p596/rojoracing53/92571ACA-022A-4C11-AE16-653BA90E90C6-159-0000000CE41F4940_zpsd9659153.jpg

But I also have my box's universal mounting plate mounted to a .125" aluminum plate that is hard mounted to the subframe.

I think I'm going to use a 32L Givi topcase along with the SW Moto rack. Says it carries 22 pounds which is a lot hanging behind the rear wheel. Ayone else run this set up and can share? Wardie

I don't care how much you shove in a top case it's a mere fraction of the wieght of a 120lb passenger. You'll most likely never even notice it back there.

Nice setup! Freaking huge though! You could almost fit your whole bike in it!

and lol Jason. That's awesome. I really need to get some sort of luggage for my bike. I want storage space!

it's more about where the weight is in relation to the rear wheel than the actual weight as long as the actual weight is overwhelming.....

Just ordered JC Whitmey top case and SW Moto Tech Alu topcase brackets. Saw another forum member using these and looks okay.

We'll know in 5 days :)

That's what I mean even if it's off the back then it's maybe double the effective weight to 30-40 become 60-80 but that's still a lot less then a passenger. This is also why my box is mounted over the rear set area, I wanted to get and weight as far forward as possible plus it looks better that way.

I totally agree with you. Wardie

Added a pair of Cortech bags to the setup:

And then I added an extra Admore Lighting pigtail to the Ninjette so the turn and brake signal kit already installed on the Givi works:
