I have the Cortech Super Mini...Its great but a little to small for me. I found a great way to mount it though. Super solid,easy and no seat interruption.
I removed the 2 nuts that hold the tank on...well not the tank but you know what I mean.
I fit the bag on then figure where the webbing will sit on those studs. I then took a center punch and heated it up with a torch to put holes in the webbing. The edges melted so that the webbing wont unravel.
Then I just bolted it on...works awesome and took 5 minutes. By the way Im selling this bag after only 1 street ride. I just need a bigger bag, its in new shape and comes with custom GS8 mounting.
