New Moto Guzzi Door Mats Available Now
This looks like it could work . https://www.rockymountainatvmc.com/parts/tusk-olympus-tank-bag-p
I use a SW-Motech Pro Daypack. It also requires the Pro Tank ring. There are also additional accessories you can add (phone case, lock).The really nice thing about it is that it's not too large, and the connection of the bag to the tank ring is magnetic, at least for positioning. It clamps onto the ring, but the magnets ensure it hooks up easily, property and securely. Removes with a pull of a strap. Great for gassing up and then reattaching quickly and easily.
I use the GIVI tank ring and have a few different bags depending on how large it needs to be for that outing.
This is the bag I put on my new Stelvio. I like the quality and features of the bag, but check the size as a camera and water bottle might be tight, depending on what you use. On my V85 I have the Giant Loop Diablo, which is a little bigger. Two things to be careful of on this bag are; the map case needs a cover since it isn't really too waterproof. The second is that the bag is so much longer it makes getting the ignition key access a little bit of a pain. All in all it is a good quality bag.
Probably could if you bend the support rod up a little.
I got you thinking, didn't I?
