The Mosko Moto Gnome Tank Bag helps riders keep essential items — like wallets, passports, water, and snacks — protected from the elements and close at hand. And just like a real-life gnome, the bag is low-profile and stout in the dirt, or anywhere you want to take it.
I was on a mission to find the ultimate motorcycle tank bag. My plan was to take my 2022 KTM 690 Enduro R across the U.S., eating up dirt roads and Backcountry Discovery Routes.
For that, I needed a rugged tank bag that wouldn’t get in my way. Tank bags are notorious for bumping into riders’ legs and midsections when standing on the pegs, so I was hoping to find something low-profile.
My approach to buying gear has always been not to skimp on quality. For this build, I wanted to stay as spartan as possible — light, compact, and utilitarian. While searching for products to help me set up my KTM, Mosko Moto became an obvious choice.
Mosko is a motorcycle luggage and apparel company out of Washington state. It has a track record for creating bombproof gear that is thoroughly tested to the extremes. The company also supports moto travelers and hardcore riders alike.
In short: The Mosko Moto Gnome Tank Bag was almost ideal for my adventures, and for shorter day trips, it’s perfect. It’s not so large that it blocks my view or bumps against my legs while standing. But aside from fitting trail essentials inside, like maps, a cellphone, and snacks, I found it too small for my camera gear, including a GoPro.
Mosko Moto Gnome Tank Bag Review

The bag’s 5L capacity fits between Mosko’s larger, 7L Nomax tank bag and its smaller, 2L Nomini tank bag.
As mentioned, the Gnome doesn’t block me or my view with its bulk, but also isn’t so small that it’s useless for carrying anything.
My 690 has a fuel tank in the rear, ignition where the tank should be, and an aggressive motocross-inspired seat. In other words, real estate is limited for luggage. But strapping on Mosko Moto’s Gnome tank bag was easy, as it fixes on directly to the frame behind the forks and subframe.
Installing Mosko’s Gnome Tank Bag to Your Bike
The Gnome Tank Bag comes with mounting straps, buckles, and zip ties. It may take some work to find the perfect spot, but when you do, you can leave the harness in place and just remove the bag to bring with you. Mosko even sells the harness separately if you have multiple bikes, so you can easily swap the bag between each one if you want.
