Dowco Fastrax Sport / Adventure Tank Bag 5 5 7 7
Alittle Pricey but worth it Over all its a great little bag to throw on and off the bike super strong magnets i can fit more than expected in it. 3 textbooks water bottle and snacks.. or complete change of clothes and shoes with extra room November 30, 2014
Great Product! I am currently using this tank bag on my 2006 Suzuki GSXR600 for a daily commute to and from work (roughly 40 miles round trip, travelling at 80-90 miles/hour on the Highway). I have been using it with the magnets and haven’t ran in to any problems as of yet despite the half plastic/half metal tanks on the 2006-2007 Gixxers. The bag is big enough to comfortably fit a pair of shoes, extra shirt, lunch and a 40oz stainless steel water bottle. It has a pouch on the front of the bag with a plastic cover for maps, GSP, cell phone, MP3 player etc. Touch devices are fully operational through the plastic. The bag also expands so you can fit more stuff than listed above. The quality of the bag looks and feels sturdy and seems like it will last a while. The bag also comes with a life-time warranty through Dawco . For anyone looking for a compact bag without having a lot of bulk, this bag is a great option! Thank you Revzilla for the prompt delivery and great customer service!! June 3, 2014
Expensive, but solid. My main reason for purchasing this bag was simple: a device window large enough for a modern smart phone. But the other features, combined with the really solid construction, make it worthwhile. The compartment area is very large (and expandable). The window is touch-friendly (though not especially swipe-friendly). The flap has inner storage. There is a permanently-attached rain guard stored at the front, which is nice. The magnets are very strong, and a security cable is included. Complaints? The side color panels are a bit gimmicky, and again the price. But you're buying a high quality product here. June 2, 2014
Lots of room great product I was very hesitant to get a tank bag but after a couple hundred miles I am very happy with my purchase would not leave home without it May 12, 2014
Loved this! I bought this right before a 1500+ mile trip and it carried all my important documents, water, big can of chain lube, toiletries, cell phone, ezpass, and even provided a nice stomach pillow for when I leaned over on the highway... Couldn't ask for anything more from this... July 8, 2013
One Tank Bag to Rule Them All! I'll be honest, I didn't shop around when I started looking for a tank bag; I simply picked the first bag that seemed to fit my general needs and boy did I end up with a winner! This bag is incredibly well-designed and every feature has a practical benefit. Take for example the simplicity of the detachable buckle keyring: simply add it to your keyring and buckle your keys in to the bag when you ride. Rain is never ideal weather to ride in, but the contents of this bag will stay dry with waterproof zippers during light rain and the sewn-in rain hood for heavier rainfall. The fact that the rain hood is sewn-in gives great peace-of-mind knowing that it won't fly away while you're riding! There's even a backpack shoulder strap that's neatly tucked away. Just take the bag off the bike, pull out the shoulder strap and you've got a free hand! Alternatively the heavy-duty handle is always available for easy carrying. A surprise benefit is the transparent plastic window on top of the bag that enables you to use a touch capacitive device such as a smartphone. This is great for navigation apps and the pouch also offers headphone ports if you want to listen to some tunes while riding. The color inserts for the exterior wells seemed a little gimmicky, but I actually appreciate the fact that the bag's highlights match my bike! This quite possibly may the one tank bag to rule them all! December 14, 2012
Great Pack I have been using this pack for about three weeks now and is has been great. The magnets grab onto my tank very well with no shifting around. It is not the biggest bag, but for a tank bag it is large enough. I also like the integrated waterproof liner that has it's own zippered section up front. I always hated having to hold the liner in my bag, it always got in the way. October 24, 2011

J P: This is an amazing bag. It fits what I need Aug 27, 2014
Jeff K: Tried it, sent it back. Got the Givi XS308 which I like much better. Aug 25, 2014
Barry C: Best reviews for a sport bike. Looks like it isn't too big and should work well on my bike. May 22, 2014
Andrew C: All the features you'd expect, but the cell phone window looks big enough to fit later model phones. May 14, 2014
Christina T: Size, features, magnetic May 13, 2014
angel b: Because of all the reviews vs my other choice has no reviews yet maybe still to new Apr 21, 2014
Christopher F: Needed a bigger tank back for my upcoming cross-country trip. Like that this has so much versatility and a built in rain cover. Apr 20, 2014
Annette F: My son liked it because it is compact and functional. He can also use his navigator when he is riding. Jan 19, 2014
A shopper asked: The description says this bag has built-in security cable. Is the cable meant to wrap around the tank, around the triple clamp, or where? Seems like a good idea, but as it is not shown in the pictures, I would like to know more about this feature. Mar 1, 2014

Vishnu H: Hmmm... I'm guessing they're referring to a tab with a D-Ring located on the part of the bag closest to the triple clamp, which you can use to add a security strap of your own, but it doesn't come with a strap. I've used a length of webbing with velcro at the ends to wrap around the triple clamp just in case the magnets let go- this hasn't happened yet, but is a good precaution to take. Apr 5, 2014

Andrew C: A steel cable with loops at both ends is included. You can loop one end around a handle and lock the other end to your bike (helmet lock would work). Or lock the zippers to one loop. Nothing very high-tech here, a $3 readily-available universal part, but probably effective. Jun 2, 2014

Vishnu H: Hey, please ignore my last response- I just realized you were asking about a bag I don't own, but was assuming the question was directed to me because of a different bag I purchased. My bad- sorry! Apr 5, 2014

A shopper asked: it use magnets or it use straps? because my bike (ktm 990 super duke) has a plastic tank. if it use magnets which one would be the best for my bike? Nov 2, 2013

Christian G: It actually has both the option of using just the magnets for easy install/removal, or both magnets & straps should you want added security...or have a plastic tank. Nov 3, 2013
Reply to Christian Good answer? Yes (1) No (0)
svillelance c: Since your tank is plastic I recommend using g the straps that are provided. I use the front strap only and the magnets going towards the seat. Nov 3, 2013

Tim B: It can use either magnets or straps. It comes with everything to mount either way. Very nice Tank Bag. Nov 2, 2013

A shopper asked: I have a BMW F700 GS - would this work for that? Also, I'm 5'2" so I'm worried about tank bags that would be come up high on me. Would you be concerned about this? Apr 19, 2015
Answer this · Send to friends Good question? Yes (0) No (0)
Dan D: It should work fine on the bike. Its magnetic and sticks pretty well. It also comes with straps. I have it on a hayabusa right now. I am 5'11" and its ok for me. The bag was a bit smaller than i would have hoped for but it is extendable and gets a bit taller. If you are 5'2" it may come below your head depending on where you head is compared to the wind screen and how you sit when you ride. Hope this helps. Apr 19, 2015

A shopper asked: I love the features that the Fastrax bags have, I tried the tailbag but it is too big for my bike. (BMW F800ST) Since the tank bag is somewhat smaller would it be possible to use it as a tail bag on my luggage rack using it's existing strap attachments? Mar 13, 2013
Answer this · Send to friends Good question? Yes (0) No (0)
RevZilla: Dowco does not recommend that you use this tank bag as a tail bag. Doing so, might result in involuntary bowel movements when you see all your personal items being crushed by the cars behind you. Mar 15, 2013

A shopper asked: Which bag has more space inside: this bag or the First Gear Manza tank bag? I like this bag a little better because I have a large phone (galaxy Note II) and this bag's accesory pocket appears like it would fit the phone for GPS. The Manza bag appears to have more space though. Also, do you carry the hydration bladder for this bag? Thx. Dec 17, 2012
Answer this · Send to friends Good question? Yes (0) No (0)
RevZilla: The capacity of the Dowco Fastrax Sport / Adventure Tank Bag is 798 cubic inches and 1330 cubic inches when expanded whereas the Firstgear Monza Tank Bag / Backpack has a 1680 Cubic Inch capacity. We do not carry the hydration bladder from Dowco but understand that most generic 1-liter bladders should fit. Dec 18, 2012

Steve B asked: Does this bag have shoulder straps or just one strap to be cross-slung? Mar 9, 2014
Answer this · Send to friends Good question? Yes (0) No (1)
Vishnu H: Mine came with just one strap, allowing the bag to be slung over the shoulder. Because of how it's set-up, it wouldn't be difficult to improvise a set of straps to wear it like a back pack- there are two D-Rings at one end (the "top"), one at each corner, and another D-Ring at the other end (the "bottom") in the center. Your question has actually inspired me to try it that way. Apr 5, 2014

Vishnu H: Hey, please ignore my last response- I just realized you were asking about a bag I don't own, but was assuming the question was directed to me because of a different bag I purchased. My bad- sorry! I need to pay more attention to the details. Apr 5, 2014
