Backcountry 35L Pannier Kit

The Backcountry pannier is our flagship product, designed for long-distance adventure touring, hardcore enduro-style riding, and camping from your bike.

With bomb-proof construction and heavy-duty materials, these bags can really take a beating. Our quick-mount wedge system makes it easy to take the panniers on/off the bike so you can store them in your tent or have them by the fire without wrestling with straps.

This is the system for long distance travelers and people living off their bikes. Guides, instructors, and RTW riders: this system was designed for you.

The Backcountry 35 was also our first product. We created it because we were tired of over-the-seat soft panniers that flop around in rough terrain, have no external pockets or stash spots, disintegrate after a couple crashes, and are a total pain in the ass to get on and off the bike. We wanted something like a backpacking frame pack, but that mounts on your bike, and that stays connected to the bike and stays waterproof no matter how many times you lay the bike down.

The BC35 is super easy to click on and off the bike, and because the waterproofing is on the inside the bag (thanks to the two-bag system), minor crashes and scuffs won’t phase this bag at all. When you think about waterproofing, external abrasion is not the end of the story, you also have to think about abrasion inside the bag. For example you might have tools, or a camp stove, or some other hard piece of equipment inside the bag that is vibrating and rubbing against the inner surface over a long period of time. That is why we use such incredibly thick, welded seam liners on this bag.

The BC35 is heavier than the Scout 25, and it’s also heavier than a traditional over-the-seat saddlebag, but what you get for that weight is bomb-proof construction and materials, a completely stable mounting system (no flopping), and lots of stash spots. Lighter is not always better if it comes at the price of functionality or durability. If weight is your primary concern, but you want to stick with a rack system, check out the Scout 25 kit. If you’re really serious about weight, take off your steel pannier racks, which shaves 8-10 pounds off the bike, and get a Reckless 80 instead. For everyone else: the Backcountry 35.

Want to protect your panniers and gear from thieves? Add a set of our Steelcore Locking Straps. The Backcountry Pannier Kit requires two 4.5' straps, mounting instructions can be found in this video.

Wedge-Mount Compatibility Note: In July 2016, we switched the backcountry pannier wedge and frame from machined HDPE to molded glass-filled nylon. The new wedge/frame are not compatible with the old version. To determine which wedge/frame you have, check on the back of the wedge. If it is flat & smooth, that's HDPE. If it has an inset honeycomb pattern, that's molded nylon. We have extra wedges and frames of both materials in stock available for order by special request.

Cutout Pannier Rack Note: Bikes with stock racks and a pannier exhaust cutout (like the R1250GSA, R1200GSA or F800GSA for example) require an additional adapter. Check the 'Hardware & Parts' section of our site, or email us with questions.

    We needed this.

    Product Creation at Mosko is an effort born of necessity. Everyone on our team rides – and time on the trail translates to an innovative, always improving product line. Crafting gear that will outperform in even the most harsh riding conditions means we make no compromise, ever.

    “So far these are hands down the best Panniers I’ve ever owned. Like most of us riders, I researched every option possible. Didn’t matter what country they came from or what I had to do to get them I just wanted the best functioning and bomb proof system around. In my opinion these are the best available.”

    Great Quality

    First of all I have to admit that the reason I have the Backcountry panniers is because I was not happy with the 25L Scouts I had originally bought. But Mosko took those bags back and gave me full credit even though I had used them for 9 hard days of riding. They then applied the credit to the purchase of the Backcountries. I have used these for a couple days of riding and am very happy with the quality of construction, ease of fitment and how solid they are mounted on my SW Motech racks. I am glad that I made the purchase and would highly recommend the Backcountry Panniers to anyone.

    Amazing quality!!

    The quality of the Backcountry panniers is amazing. Extremely robust, well designed and easy to customize with the molle system. Quality control is top notch, not a single production flaw on the entire set. Very impressed with the way these are built, military grade quality at least. So much better than aluminium panniers for offroad riding, these will not bend or leak. I will buy more Mosko Moto products in the future for sure. Keep up the good work Mosko team! 👍🏼👌💪🏼

    Pannier set 35 liter

    Crazy days in the Alvord desert !

    Been having a great time on my KTM Super Adventure 1290 r and decided it was time to do some longer trips. Talked to everybody I know and did a ton of research online and heard Mosko moto was the way to go. Especially with what I planned on doing with this bike. I took off to South Eastern Oregon to the Alvord desert dry lake bed. The forecast wasn't the best but I had the time and wanted to go. After one day of riding at a hundred miles an hour plus across the Playa it started raining at 3 in the morning. It put down 1.2 inches of rain that day and I was screwed. The next 8 hours was some very serious riding in slicker than snot conditions. I lost it at the end and couldn't get my bike up. My Mosko Backcountry 35 bags were the absolute bomb! They slid right off and sat in 4 in of water for several hours until I could get rescued a half a mile out on the lake. Bomb-proof design, could attach multiple items all over the outside of the bags. The inner liner dry bag and design Cap all my gear tidy and dry in the utmost nastiest conditions. Would highly recommend these two anybody that is doing hardcore serious adventure riding. Five stars for sure! @nutz42wheels


    So far totally happy. It is a little tight on the right side where the latch just misses the passenger grab rail on my 2013 BMW GSA.
