AltRider Hemisphere Tank Bag

The AltRider Hemisphere Tank Bag was designed for trips to the store down the block to long-term treks into the wild. Haul what you need, when you need it.

The spacious main compartment has a capacity of approximately 11 liters, plenty of room for those items you need to access quickly and easily. A burly metal snap allows effortless opening and closing, even with a glove on. The ballistic nylon webbing ensures long-lasting durability of the snap closure. Removable dividers allow you to customize the compartment, and an interior waterproof liner with fully taped seams completely isolates your kit from the elements. The liner can be left open for easy access, or sealed using the roll-top closure for complete protection.

The deliberate shape of the tank bag is designed for use on multiple types of motorcycles. It won’t interfere with the vent hose on dirt bikes, allows easy access to the ignition on larger bikes and doesn’t impede the controls on motorcycles. The proven harness attachment allows for easy fueling and is attached using ballistic nylon webbing straps and high strength Delrin buckles. Sleeved harness straps are located under the main compartment for smooth, secure attachment to bike with no exposed buckles, nothing to bother riders’ legs in a standing or seated position. The tank bag is secured to the harness with a robust YKK zipper, allowing easy removal of the bag.

The versatile tank bag also features a map pocket  accessed from the inside, allowing for maximum defense from the elements. Many other tank bags zip from the outside which allows more moisture to get trapped in. Tough marine-grade vinyl is used for the face, making it UV-resistant and easy to see through. A small stash pocket is located on the exterior bag for temporary storage of quick-access items.

The Hemisphere Tank Bag is constructed from 1050D Ballistic Fabric, uses military grade stitching and all straps are full-strength nylon webbing. Reflective logos on either side of the bag provide increased visibility and safety in low-light or night time riding conditions.

AltRider Hemisphere Tank Bag 4.7 5 3 3
Love this tankbag Not the biggest bag, but the best tankbag I've purchased over the last 40 years of riding! Shows made in U.S.A. still means something! September 8, 2014
good but could be improved. Tank bag is very well constructed overall. The only short falls are: 1) organization dividers look super cheap and flimsy. I will be surprised if they hold up for very long. 2) single button closure feels insecure. August 18, 2014
AltRider Tank Bag on BMW 800GS I had been waiting for the AltRider Tank Bag to come out and it was worth the wait ! Installed it on my BMW 800GS in about Ten minutes. Great looking bag and fit the bike well. I like the zip off feature, water proof liner, map loads from inside, and one hand open feature! And its made in USA! Cost is high but well worth it.

Robert F: While I can't answer for certain, I would be surprised if it wouldn't fit. On my 2014 F800GSA I ended up cutting off 6 to 8 inches of excesses straps. The tank curvature is fairly mild on the k75 so I would not be concerned with zipper binding. Jan 30, 2015
