Incredible Versatile Tank Bag
This bag has quickly caused my saddlebags to fall out of use. It can be converted from an incredibly roomy tank bag to a compact backpack in under 10 seconds, is well built, and looks great. Great for when you don't want to have to leave things unattended on your bike when parked.

To my surprise, an iPhone touch screen can even be used THROUGH the map pocket's translucent screen. No longer have any need for a GPS or similar bar-mounted navigation device.

The extra straps, well organized interior, ability to expand, and attention to detail in the construction are just excellent cherries on top.

If you are trying to decide between the 12L bag and the 18L bag, you should go for the 18L. It is equal in size to the 12L but is able to expand a significant amount. This means that it remains as compact as the 12L when you need it to, but always gives you the option of having significantly more storage space.

Fantastic Bag
Full disclosure requires that I confess this is only the second tank bag I have ever used.

My first bag, the Wolfman Rainier tank bag, I purchased in March of this year. That bag was a strap-on. I mention this as it plays a part in my review below. Also, I ride a 2015 Triumph Daytona 675R - so a supersport bike.

I purchased this Cortech Super 2.0 18L tank bag due to the reviews and because it was a magnetic tank bag.

- Nice finish
- Even when empty, maintains its shape and looks sporty
- incudes a padded sleeve to hold a second faceshield (I always wear tinted, so nice that I can store a clear visor for night/rain/cloudy scenarios)
- EASY-ON and EASY-OFF - I didn't think this would be that big a deal to me, but it's actually very nice (of course any magnetic tank bag would do the same - but still, it's a positive). To contrast, with my Wolfman Rainier I had to attach straps to my bike to which the strap-on bag would attach. When not using the tankbag I had to purchase a stretchy "x-strap" that would hold down the bike-attached straps or otherwise I would have to deal with them flapping about. I lost my "x-strap" recently and it was that which precipitated me purchasing this Cortech bag. I purchased a strap-on bag because I had been warned that a magnetic bag would greatly increase the risk of damage to my finish on my fuel tank. What I found instead was that the strap-on Wolfman Rainier messed up my finish due to the straps rubbing. :-( Only time will tell, but so far I am not seeing any reason to fear that this Cortech bag will scratch my finish. (but I would have said the same about the Wolfman only 3 days into owning it)
- The built-in handle is very nice. The one on my Wolfman Rainier became very stretched out. This one is tight and it looks to me that the way it is made that it will stay tight.
- The backpack feature was a must for me. The Wolfman Rainier backpack solution was a joke. They sell an extremely overpriced nylon strap solution and it was always slipping off my shoulders. Also, for multiple other reasons, the whole thing just didn't work really - it was clearly an afterthought solution. On the other hand, this Cortech bag is very nice. I was initially worried about the built-in straps. I worried that they would bunch up when tucked away, preventing good contact between magnets and fuel tank, and I also worried that they too would slip off my shoulders. While I think even Cortech would admit that this is not on par with top-level dedicated backpacks (in term of strap padding, and overall comfort, I have found this bag to be VERY GOOD when used as a backpack. None of my fears have been realized, and it has been a joy to move from tankbag to backpack and back again.
- The expansion solution works very nice and it is tucked away when not needed (as compared to my Rainier where I was always grabbing the expansion zipper rather than the zipper to open the main compartment).

- The zippers have these little cubbyholes (not sure what the real term is) for when they are zipped up. This, I gather, is so that they do not flap about. But, those cubbyholes were designed too tightly and it takes too long to get the zipper tucked into them (and so I don't bother). Perhaps they will loosen up over time, but I suspect not.
- The key solution located within the main compartment is, I think, useless. The plastic "hook" is difficult to use, and even if you attach your keys they simply flop around in the main compartment - just on a tether. The main compartment is not so large that I can imagine keys getting lost. Perhaps some will find value in it, I just think it needs to be rethought or removed.

The two cons I raised are slightly irritating, but in no significant way do they detract from my enjoyment of this bag.

Very pleased owner.

Get this instead of the 12L bag!
This bag is the same exact size as the 12L bag, with the option to unzip and expand to the larger 18L. Fits on my tank perfectly and the magnets firmly secure it. Comes with a strap to attach it to the handlebar for security while riding. I used it the first time "just in case". The bag didn't move at all, so I don't use the strap anymore. When I get to my destination, I can just grab the handle and go...the bag slides right off the tank. I haven't tried the hidden backpack straps yet, but it looks like they'll work just fine.

Great bag!
Let me be clear -- I am reviewing the magnetic version of the Cortech Super 2.0 18l bag. I have no reservations about recommending this bag. Expanded to 18l it holds a ton of stuff, and it grabs the tank securely every time, with no movement at any speed. If you aren't hauling a lot of stuff around, leave it zipped to the 12l size to save some space. The map window is fairly useless, as the entry opening is far too small to get a decent sized map in, but other than that, it performs great.

The same cannot be said for the strap version, which I also have (da** BMW plastic tank covers#. No matter how tight you pull the straps, the bag flops around even with a light load, but the same can be said about every other strap bag I've tried #a bunch). If you have a metal tank and don't need a map window, grab this bag. Otherwise, pass.

Good Tank Bag But Not Perfect
I wanted a tank bag that was easy to take on and off, had enough capacity to hold my bike cover, and something with enough room that on long trips I could move some of my excess luggage from my backpack into the tank bag. Overall this definitely fits the bill! I use my bike as a mode of transportation between home and college (round trip of 240 miles) and this tank bag has proven its worth. Overall I've probably ridden about 1200 miles with it. As far as the specifics:
The Good:
-Magnets work well on my bike (when the bag is not overloaded). I ride a 2007 Kawasaki Ninja 650r. I've ridden on highways and side roads and the bag stays where it lays.
-A fair amount of capacity. I can fit my bike cover and cram in 2 chain cleaning/lube bottles.
-Seems to be very durable construction. Nothing cheap about it.
-The backpack feature is pretty cool. I haven't used it much but I can see how it would be useful (it's not just a gimmick).
The Bad:
-Although it is nice to have the option of expanding the capacity from 12 to 18L, in practice it doesn't work so well because the side flaps, containing some of the magnets, don't have enough contact with the tank for a good connection. Thus, it's not possible to use all 18L of space. If Cortech had just made the flaps a little longer maybe this problem could have been avoided.
-The map case is OK, and I've definitely used it, but you have to fold up the map quite tightly to get it to fit.
-I think the bang for the buck of this bag is OK, but I think that $125 is a little steep considering that Cortech sells the Cortech Super 2.0 Saddlebags for a little over $140.
Definitely a good little tank bag. Solid construction and magnets work well as long as the bag isn't stuffed to capacity, in which case the bag may shift a little. If your in the market for a tank bag which has decent capacity and is easy to take on and off, then this bag will work well. If your just concerned about the amount of storage, I would look at the Cortech Super 2.0 Saddlebags which are only about $10 more expensive, has more storage, and definitely better bang for buck.

Nice tank bag but maybe not for my bike
Fit/finish are good. I like the expandability and the lens pouch is a nice touch. I had one issue but it may be due to my wide tank. I was going about 50 and the bag came off my tank. I pinned it between my knee and the tank. It happened twice. The second time I noticed it was catching air between the tank and the bag, peeling back the magnet. My son has had no problems with it on his Harley

Great Bag With Convenience
Have done multiple trips cross county on my Harley Ultra Classic but never with a tank bag. Can't believe it too me this long to get one. Using the magnets it clung to the tank in a secure fashion as long as it wasn't too far forward. Positioning it too far forward caused air to get caught underneath (regardless of fairing) and lift up. Plenty of room in the bag for water, camera, food etc. The clear map pocket on front is good but it's tapered at the top so if you want fold paper in half to get the full length. The rain cover worked well but fills up in the wind no matter how much you tighten the straps. Not sure about other bikes but my handle bars do hit the bag on very tight turns. I've been wanting taller bars so now is my excuse to get them. The back pack straps work great and use the bag as my camera and walk around bag. Despite the "minor" stuff it does what it says it will do and it is now part of my permanent "set up".

Great product, love the magnetic base and would definitely recommend this product.
I'm a daily rider and I wanted something that would detach quickly and have expandable storage for my rain gear. I was hesitant on getting a magnetic based but I am very pleased with it. The grip on the tank is very stable and there is no movement even at high speeds. The expandable storage is great when needed is still comfortable to reach around. I have some time in the rain and haven’t notice any leaks yet.

Perfect for my Speed Triple
I use this to commute to work. When expanded it is large enough to carry my dress shoes and uniform. The side compartment zippers are also easy to access while wearing leather gloves and I use them to hold my id card to get through the guard gates. The inside of the bag has rigid flaps the flip out to provide shape and to support the bag when expanded to full capacity. The magnets hold the bag securely to the tank even at speeds >80 mph. Also, the bag is attractively designed and looks good on the bike. Grabbing the handle to pull the bag off the tank will cause the magnets to attract together, which prevents dirt or dust from getting on the surfaces that will make contact with the tank. Overall, the bag has made it very convenient to use the bike for quick trips to the store or commuting to work. I can't speak for the map pocket since I have not used this feature.

Very Pleased with the product
I bought this for my son for his Suzuki SV650 and was very impressed with the quality of the bag and the thought that was put into it. The rain cover is located in the back of the bag easily accessible if you have to quickly pull over and cover. The side pockets are somewhat rigid so as not to accidentally crush contents such as sunglasses. The inside of the bag is expansive and the cinch bag within allows for ability to almost have a dual pocket where you have your immediate need items outside the internal bag and the longer need items inside the bag and therefore not mixed. The organizer built into the lid is fantastic as without something like that stuff just gets lost everywhere in the single storage area. The map pouch is nice although in a day where almost all of us either use our phone or a gps for map data I would prefer having a way to more easily attach a phone to the top instead of a physical map. However, a phone will slide in the map pouch and is usable through the plastic pouch.

The magnetic attachment works great and the hidden backpack straps is a nice touch especially if you are placing a camera or video in it for sight seeing. Allows you to make it double as a camera bag.

All in all great bag and quality made. I would highly recommend it. Oh, and not so tall that it feels like it is in your face while you are riding either.
