We bought this bag to put on the back of my wife's 650GS twin. She loves it! And when moma's happy... everyone is happy.
It has plenty of pockets to segregate all her essential riding gear (e.g., iPod, intercom and radio, hair stuff, frozen water bottles, a couple of extra layers of clothing, etc.).
If I hadn't already purchased a hard case for the back of my GS, I'd also own one of these bags.
The bag comes with an assortment of various length straps. I can't imagine not being able to get a good fit onto any bike.Rating: [5 of 5 Stars!]
