This is the biggest jetstream PERFORMANCE option you can get.
Now I have a large and medium size Axio bag. You better get them, or at least one, while they are still around: there's nothing else close on the market now, before, and maybe never will be (for some unknown reason, other than the 'Man' does not like motorcycles riding stable and vibration free at high speeds.)
The Axio Forza (bottom bag below) is sold in Europe ebay for about the same price as I got a new used one here. It's a medium size bag not sold in US originally, and is actually better quality than the slightly larger and more expensive Axio Swift 2.0, top bag below.
The biggest and best hardpack made, the Axio Swift 2.0 - the top bag below, is here and there but edging higher in price. I still have one after 8 years of bicycle sweat in FL, and 2 zipper lives, so I'm getting a new one before they all disappear (and mine needs at least $80 shoe-shop repairs --> bicycling with heavy text books in 90 degree humid weather in the FL Sun is Hell)!
The Swift 2.0's available now usually have Commercial Name brand marketing on them (or they were hacked up by a creative genius Harley owner :-) The interesting thing about the Yamaha bag is Axio First worked with Yamaha to determine the 155 mph max stable limits of the Axio bag. I was planning to put red reflective 3m tape strips crossed around the top center protrusion on the back: I hope no one tries to take it away because it resembles a(n inverse) rebel flag!
