Perun moto BMW F900GS Top luggage rack with Kriega US-10

Kriega US-10 Drypack falls in a "small tail bag" category. 10 liters of capacity is enough to transfer basic tools, first aid kit, rain gear and some snacks from backpack to the back of the bike. Being fully waterproof makes the US-10 usable in any conditions.

Perun moto BMW F900GS Top luggage rack is primarily designed with off-road performance in mind, meaning it's small-ish and lightweight. Rack has pre-drilled, countersunk, holes for installation of Kriega OS-Rack loops.

OS-Rack loops mount to the underside of the rack (with M6 countersunk bolts), leaving top surface completely flat. One end of Kriega G-Hook straps hooks onto the rack loops, other end buckles onto the bag. This makes for an easy and fast installation.

When installing the OS-Rack loops, it's a good idea to use nylock nuts on the underside (unlike what's shown in the photos below :D ). This will ensure they not fall out. Just keep in mind not to overtighten the OS-Rack loops, they should be able to rotate a little. Other option is to use mild thread locking agent.

I prefer mounting the US-10 bag across the rack, with opening to the right side of the bike. This gives easier access, and will prevent stuff from falling out to the ground. Mounting the bag lengthwise is also possible, but there is a chance it might move back-fort during braking and acceleration.

Here is a short video of Kriega US-10 Drypack mounted to BMW F900GS with Perun moto BMW F900GS Top luggage rack.

And following photos show it mounted to the bike from various angles.
