I went with the RevPack Jr. After about 1000 miles, up and back to Laguna Seca, I am very pleased with it. Well made but very simple, no extra pockets or anything like that. The bottom surface was a sort of rubberized vinyl that I decided wouldn't scratch the cowl---and it didn't. The bag fit very well, attaches easily, didn't shift around at all, and really looked like it was made with the Monster in mind.
To give you an idea of capacity, I was able to put in it a windbreaker, two pair of jeans (one lined with Aramid), two nylon hiking shorts, two long-sleeved tees, two short-sleeved tees, two tank-tops, two pair socks, two underwear, tennis shoes, Teva sandals, helmet bag, shaving kit, ss coffee mug, one-cup 120v heater, tea and tea-ball, smallish lap-top computer, assorted cables and chargers, maps, notepad and pens. Ok, it
was a tight fit, but the zipper closed...
I also rode with two small Chase Harper barrel bags, one on either side of the bike hanging on the grab rails. In one, I put a bike cover. In the other, all the little stuff I wanted handy: camera, cell phone, wallet, spare change, chap-stick, sunglasses. I also have a very nice Marsee tank bag, but I found I didn't need it for this trip given the space of the Revpack.
