I bought the medium bag to use on my KTM 950SM to ride 500 miles each way up to Monterey for MotoGP. It worked great. I love the attention to detail and great construction.
When properly strapped down, it is rock solid and, unexpanded, had plenty of room for six days out of town. I liked it so much I bought one for one of my riding buddies, when he wouldn't let me pay my half on a shared hotel room. (He likes it, too.)
Definitely one of the best on the market. (Posted on 8/19/11)
I have had an eye on this bag for a while but did not have a trip planned. We recently did plan a trip to Oshkosh and around Lake Michigan on our bikes. Due to a health issue the trip changed to cars, but I had ordered the bag anyway. It works really well strapped on the luggage rack of a Morgan +8 as well as a bike! I was able to carry everything I needed and it was easy and quick to remove at the end of the day. I highly recommend this series of bags and only wish it was waterproof,putting the cover on for a pop-up shower was a pain. (Posted on 7/31/11)
I have a 2008 Suzuki M50 and the medium size bag is my everyday bag. I have a steel thermos I commute with and the built in holder is perfect. The medium Motofizz bag (unexpanded) holds my workout bag, my padded jacket, vest and a half helmet. Expanded you can add so much more to the bag, the expansion is very generous. I have a separate laptop bag only for easy removal from my sissy bar; I could fit my laptop bag in my medium Motofizz when expanded. I don’t think you’ll need the large bag. Major downside: it isn’t waterproof. I have to put a plastic bag over it when stored outside so moisture doesn’t seep in. (Posted on 7/1/11)
I purchased one of these a few years ago and it has never failed to meet my expectations. It keeps your gear dry, is easy to access while lashed to a bike in foul weather, it has plenty of room and is well made and sturdy to boot! I got the medium size because the length when extended was the same as my tent so that I could put it inside and have less clutter and less equipment exposed. Would I buy another one? Yes! Does it have a downside? Only if you can't resist the urge to take with you more than you need! (Posted on 3/18/11)
I'm very disappointed … that they changed the color scheme. The black/silver matched my BMW F800ST so well. The new black and dark gray is just not as good looking. Other than that, it's a GREAT bag. Solid, stable, and well built. I have the large (great for camping and long trips, but too big for day to day use. I also have the small. Great for a day trip but a little small for my day to day commuting needs (cold weather gear, rain gear, etc.). This is my "almost every day bag". Best rear bag I have had yet and I have had many!
