I got these from ridebikegear. I think they are also sold as Mutazu. 22"X14"X8.5". They were about $300. I also bought a universal quick release bracket set for them from ridebikegear. I fabricated brackets to lower my pipes 3" at the tips. I attached a stainless steel 10 gage plate to the backs of the bags for reinforcement. The SS plate is cut in the contour of the bag and covers the entire back. The bags are hard plastic and seemed to be sections glued together. So the plates strengthen the construction and gives a stronger contact point for the attaching bolts to avoid cracking of the plastic. I haven't hooked up the wiring yet, but I'm planning on wiring my brake light to the built-in blinker on both bags so that, initially they light up when I brake and then start blinking if I stay on the brake.
