(10 customer reviews)

From: $250.00

It’s never easy making a great piece of kit like Giant Loop’s Diablo Tank Bag even better—but we did it!

Fully redesigned for 2021, this new little devil emphasizes increased waterproofness while maintaining its many rider-friendly features: a low-profile shape that stays out of the way, a pliable yet rugged structure, and quick, easy access to fuel fills. The redesigned Diablo Tank Bag is the slim, bulletproof, waterproof, adventure-ready tank bag for those who want to ride fast and far with zero distractions.

To protect surfaces against scuffing or marks, we highly recommend installing Vinyl Protective Film beneath where tank bag makes direct contact with body panels and plastics.

Pannier Pockets™

Giant Loop's minimalist version of tank panniers, our Pannier Pockets integrate with the Fandango/Diablo tank bag harness to expand front of bike storage without getting in the rider's way.

Giant Loop’s 6-liter Diablo Tank Bag delivers rider-friendly features like its larger counterpart, the Fandango while maintaining a minimalist, slim and trim design. Even when standing on the footpegs and riding off-road, the Diablo never gets in the way, thanks to its compact design.

The Diablo fits virtually any dirt bike, snow bike, enduro, dual sport, adventure, or street motorcycle because of its versatile, universal harness mounting system that straps to the frame. The bag can be partially unzipped from the harness to access fuel fill or completely removed and carried by the handle.

Photographers love the Diablo tank bag because of the interior’s hook-and-loop material that is compatible with many camera bag dividers, and for ease of access to the bag while seated on the motorcycle.

Combine the Diablo with Giant Loop Pannier Pockets™ and Zigzag Handlebar Bag™ for even more on-the-trail storage volume.

  1. Alan Brumley

    Love this tank bag. There’s a zipper catch on the left side that keeps the zipper from unzipping. It works well. You can partially unzip the bag and it will flip out of the way so you can get to the fuel cap. You can also fully remove the bag if you’re heading into a restaurant on your ride and don’t people running off with the bag and contents. The straps will remain behind and it’s as hard to re-attach the bag as it is to zip up a jacket. if you live somewhere warm, I would think twice about leaving a phone in the clear top of the bag. The sun and heat from charging your phone while in there (you can route power into that pocket) may cause it to overheat. That clear top pocket is really better for a paper map or turn list.
    The walls of the bag are nice an thick and really protect whatever you have in there. There is a moveable ‘wall’ of the padding material that you can move, so the bag really has two internal chambers. That will keep your phone from smashing into your point and shoot camera in the bag during the turns.
    All in all, the bag is a solid piece of luggage. I haven’t taken it through the rain, but I’m confident it’ll protect pretty well but they give you a water tight bag to put your stuff in to be sure.

    The bag is fantastic! I really like the hidden pocket under the bag, great place to keep registration and insurance without them getting torn up.

    I added the two side bags as well. They hold quite a bit as well.

  3. Mackenzie Regner

    Very nice fitment on my KTM 1090 adventure. I like being able to zip it off to the side for the gas cap really easy. Super nice build quality

    This is my second GL tank bag, I had the Fandango on a previous bike that was sold with the bike. They have definitely beefed up the construction of these bags. The construction seems to be pretty much indestructible. The YKK zippers are easy to operate and very good quality. For a bag that holds all my essentials, it is low profile and doesn’t get in the way while standing. Also, it’s easy to unzip 2/3 and flip out of the way for fuel tank access. There are so many well thought out features to this piece of gear, I haven’t even put all of them to use yet. I’m looking forward to having this on many adventures to come!

  5. Jarrod Chapman

    I am very impressed with the quality of this tank bag and happy that this was the one that I settled on for my adventures. It is the perfect size for the gear that I need to keep close at hand and small enough that it’s not in the way when maneuvering technical sections. I’ve not tested it in a full downpour yet but I’m confident that it will shed water and protect my equipment. I appreciate all the thought that went into the design such as the adjustable interior, the large zippers that work well, all the pockets, and it even comes with a zippered dry bag for added protection. Very pleased.

    Diablo Tank Bag is perfect for my WR250R. Looks great. Works great. Very happy with my purchase.

  7. Brian Cassidy

    I’ve recently purchased and been using the Diablo Tank Bag and the Zigzag Handlebar Bag on my Tenere 700. They both have been great and the high quality is evident! The easy access to the gas cap with the tank bag is a big plus… just a quick half-zip around and the bag folds out of the way for access to the tank cap. The diablo is a great size and stays out of the way when standing off road. I have the zigzag bag mounted to the crash bar for some tool storage that is out of the way and placed down low. Very happy with both products from Giant Loop!

    I just installed the Diablo tank bag and I am very impressed with the construction and the ruggedness of the materials. It also looks great, especially in grey! The Diablo tank bag is a very well thought-out piece of luggage! Love it!

  9. Patrick

    I researched quite a few tank bags for my KTM 1090, and landed on the Giant Loop Diablo for its superior design and fit on the bike (check out Revzilla’s review). The bag is incredibly well made and thought out. I love that I can easily unzip it half-way at the base to access my fuel fill, or fully-unzip to remove it from the bike. The pockets are great, especially the secret document holder, and I appreciate the webbing for small item storage on the velcro divider. The bag is big enough to hold my 20oz water bottle and more, but small enough where I don’t notice it while riding. The quality alone has impressed me enough to continue choosing Giant Loop for my luggage needs.

  10. Trisha Marshall

    I got this bag for my 2016 Suzuki DR-Z400SM, and I love it. It was pretty easy to install, and it doesn’t get in the way when I am riding. I love that you can easily remove the bag from the harness. I am also impressed with the overall quality of the materials.
