DESIGN

The Trail 16L features two five liter side bags, expandable to eight liter, made from DWR-coated 420D nylon 66 ripstop fabric mounted to a custom CURV® composite harness.

With the capacity to fit two 1L MSR fuel bottles in each five liter bag in the standard low-profile configuration, the bags quickly expand by an additional three liters via a DWR-coated YKK zipper expander panel with glove-friendly zipper pulls to accommodate additional items like a tow strap, hand saw, jacket, and tubes.

At just three inches high in standard configuration and five inches high when expanded, the low-profile construction of the Trail 16 keeps the bags hugged close-in to the bike and allows riders to slide over the bag for pivot turns when terrain gets techy.

This bag can handle some light rain showers and splashes from stream crossings but is not waterproof. The DWR-coated coil zippers are covered by storm flaps, and the DWR-coated nylon ripstop fabric sheds droplets, though this bag is not seam-sealed. If you're planning on riding in the rain and need to keep items totally dry, we suggest putting them in a small dry bag inside the Trail 16L bag or checking out our 100% waterproof Reckless 10 system.

The CURV® composite harness material provides a rigid, rackless, universal mounting system that attaches to the bike with four cam straps, allowing the Trail 16L to easily transfer between different bikes. The rear of the harness has multiple mounting options: choose from the included webbing cam straps that wrap around the fender or tail rack, or use the included aluminum Cleat Kit tie-downs to attach webbing straps to rear fender top. The harness also comes Gnoblin-ready for those choosing to upgrade from the standard rear webbing straps to our stainless steel quick-mount system.

The Trail 16L has two width settings, narrow and wide, providing fit options for small enduros up to larger ADV bikes. The center of the harness comes with pre-cut slots for Voile straps, providing the option to stash a jacket, small dry bag, or additional fuel bottles.

The two-piece harness is backed with removable closed-cell EVA foam, which provides a replaceable wear layer to help protect the bike and harness.

If you have a bike whose tail pipe gets super hot, we've included a laser-cut anodized aluminum exhaust Heat Shield with band clamp attachment to protect the bag and exhaust.

Weighing in at just over 3 lbs, Mosko's lightest luggage system is a streamlined trail bag designed for all-day singletrack rides that require additional gear-carrying capacity.

IMPORTANT NOTES
  • Exhaust heat damage is not covered under warranty. Please use the included heat shield and follow the installation instructions carefully.
  • On dual-exhaust bikes or bikes with especially high/exposed pipes, you will need a second heat shield, available for purchase in our website's Hardware & Parts section.
  • Contact between soft luggage (no matter how soft) and your bike's plastics or painted surfaces will cause cosmetic wear to the bike over time because accumulated dirt is abrasive. If that is important, try applying a clear protective film (like Allstar Performance Tape or 3M Polymask Protective Tape) to your bike.
  • Different bikes and installation approaches present different wear points to the Reckless Trail 16L harness. After installation, go for a short test ride, then check for wear points. Adjust the harness position, file down sharp rack edges, or apply a sacrificial wear patch as needed. Continue to check for high-wear points over time, but remember that the harness is made to take a lot of abuse. Some visible wear is normal, and in no way does it affect the strength or waterproofness of the luggage.

Great bag

I have been using on my KTM EXC-F for a few months. Gnoblin system is worth it. For sure it’s pretty water proof. Stays tight to the bike.

Best dual sport investment. After years of riding with all that extra weight on my back. I finally came to my senses.

Motorcycle fitment

The quality of the bags, including the carrier, is high. I ride a KTM 890R and it doesn't sit well on the motorcycle. I now need to make adjustments so that the system sits well on the motorcycle. It's a shame you don't explain to your customers that adjustments need to be made after purchasing the 16-liter system for the motorcycle in question.

Mediocrity elevated by hype

The mountaintops echo with the ecstatic hollers of riders praising everything Mosko, so I was excited to try them out. Tldr: From my perspective, there are more adaptable, lightweight and modular luggage options available for much cheaper (albeit with less slick marketing), and most seem less likely to crack your Tenere plastics.

I installed the bags on my ‘25 T7 before a trip to Moab. After testing them on my commute a few times, I rode Slickrock Trail, as well as White Rim and other nearby trails, typically carrying 2L of extra water in a bladder on one side and a few pounds of emergency supplies on the other side. I did not need to expand the bags to carry this lightweight day ride setup. In total I have just under 1,000mi on these bags in a wide variety of conditions, but nothing abusive. I wanted to try these out on my 450 as well, but unfortunately they wore out first.

My notes:
- Shipping from Mosko direct was slow and I had no time before my trip to reach out after discovering my package was missing some hardware. Based on what I hear from other riders, Mosko probably would have shipped me the missing hardware without much fuss. Particularly irksome was a missing exotic shallow-pronged t-nut. Order early and check package contents upon arrival.
- Fit on 2025 Yamaha Tenere 700 is OK (I used the “Wide Setting”). The bags fit, but the semirigid harness design prevents you from locating the bags lower and more forward for better weight distribution, or to make room for other cargo.
- Unless you dangle it off the back, the harness also prevents you from removing the seat, which is a bummer because I stash stuff under there. The dimensions try to accommodate every bike from a 150 to a 1300, across all riding styles, with and without pillion passengers and other cargo, so the fit can’t be ideal for any particular scenario.
- As you ride, the setup settles, resulting in slack straps. A more refined system might have elastic in the straps that takes up the slack and keeps tension in the system as settling occurs.
- The bags look the business when the bike is parked but they look super goofy flapping around like chicken wings while riding. The harness is effectively a spring; i.e. it curves around your fender due to weight and tension from the straps, but when the straps get loose, the harness wants to flatten out and flap around even with very little weight attached. You feel it back there. (I’ve taken to calling this dance move the “Mosko flap” as it’s even more pronounced with the larger Reckless setups)
- Tightening the straps reduces the flapping somewhat, but after a short amount of relatively smooth gravel riding, both rear plastic side covers on my Tenere cracked under the pressure (again, always loaded very light). You might fault Yamaha here for the brittle rear plastics that are somewhat pyramid shaped, so all the pressure from the harness is on a single point. I would also fault Mosko for the semirigid design that does not allow the harness to conform around the shape of the bike, rather it teeter-totters on the tip of that pyramid (see photo).
- Yes, I bought and tried a Gnoblin to accompany these bags. Save yourself drilling into your fender - the Gnoblin is a gimmick primarily designed to lock you and your bike into Mosko’s system, not to lock your bags onto your bike. The bags include rear straps that wrap under the rear fender (no cutting required). If you want to speed up removing and installing the bags, simply trim the rear straps to size so you don’t have to spend forever tying away your excess strap length.
- I appreciate that every strap includes a velcro loop to retain that excess strap length, but IMO there are faster / more secure options like web dominators. I had one of the velcro loops come open (I probably kicked it open by accident while throwing my leg over the bike) and the excess strap length was dangling dangerously near my chain.
- While the Gnoblin is a costly add-on, the included exhaust heat shield is completely unnecessary on any low-mounted exhaust, and the included clamp was not long enough to reach around the (admittedly huge) OEM exhaust can anyway. Expensive scrap.
- The quality of the stitching is knockoff grade, with many loose threads straight out of the box. The stitching on the front left strap is failing after less than 1,000mi carrying a light load.
- The branding on the bags is…bold, for good or bad. That said, the stickered-on patterns on the harness, the lizard and such, disintegrated and peeled off before I even installed the bags on my bike, blurring the line between disposable packaging and product.
- The bags have fiddly velcro that covers the zippers, but are not remotely water- or dustproof. You should leave them open to evaporate water away afterwards (or else…mold).

I will be giving the bags to a Mosko zealot who has patience for warranty back-and-forth.

Supreme design

I’ve owned 40L rackless for 5 years. I know the quality of mosko well. When I bought a te300i, I wanted something smaller. When I saw the video of the 16L, I was hooked. I have them now and they fit so well on my 300. You can tell these things are designed by people who use them. Other riders have fallen in love with the way they look and work. I’ll prolly get a second set for my 500 and use it on it.
