In some areas of the country, the smallish 3.9 gal fuel tank might be a problem.
I use a Cortech tailpack for multi-day trips and I've finally figured out how to keep the bag mostly in place when I open the passenger seat to refuel. I had to build purpose-specific hooks that use existing bolts for my Givi box racks. Now on my 2nd trip, I have some ideas on how to refine those hooks. :-)
