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 3.6 kg 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 1.4 m 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."

    lesson learned

    Purchased lesser over the seat saddlebags before coming to Mosko. Easy install, heck for stout product. Should have come this way first time around for my 1090. These bags would have held up on slow spill, baby head rock, 4wd down hill trail near "Race track" in Death valley. First trip with Mosko bags was to Laguna Seca July 12th races. 650 mi. Held everything for short o' nite camp trip with room to spare.

    Great Setup!

    Bought the 35l panniers back at start of the year for my 2015 Yamaha FJ09. Just returned from a 5200km trip from Toronto to Mt Rushmore and back and these bags rocked! Easy off/on. Easy to pack. Held camping gear with plenty of room. They DO take some breaking in. No issues. Did test in the wet, and they performed as they should. Would recommend.

    Perfect Bags and light too

    Lots of people complain about the weight of the BC35s. But if you look at other 70L storage solutions they are light. And they have the fuel bottle holder at the back.

    You take other companies 35L throw over panniers and then add 4 extra fuel bottle holders and you are at the same weight as the BC35s with way too many straps.

    The BC35s have the ability to move the weight you carry down and forward on your bike as long as you build a rack that places them in tight to the bike.

    We have 8000km on them on or wr250r and xt250 and love them. So slick
