So on your first question, I've got an SW Motech adapter plate that sits in top of the normal ducati top box plate. Then my givi top box clicks straight into that. On your second question, maybe its just the angle of the pic but I don't have engine bars yet, so no bag. If you're looking for a small, handy day bag I'd suggest any of the givi tanklock range. Solid attachment and in my experience, they don't interfere when you take the bars from full lock to full lock.
That's finest sheepskin, thank you very much! I have a sculpted seat so need some er... Extra comfort
as you quoted me and I DO have crash bar bags...I'll answer they are Small Ortleib bags that were originally BMW Adv crash bar bags that I had on my.....you guessed..BMW GS Adv being tight, Ive adapted them to fit the Givi crash bars, they dont get in the way at all and allow me to carry various items like jump leads, fuel syphon, tow strap etc without impacting on any storage in the panniers/top box stylish tho..they aint !
