Here is one of my Ducs. 2009 hyper 1100.
Gotta be one of the funnest bikes I've owned. I'm on a month long touring trip on mine. Picture above is how its set up minus my soft side bags.
I say get the 1100. Dont worry about the upgraded versions. To close to each other that on the street its not going to be noticeable.
Some pit falls... some have leaking head stud issues. Some gas tank warping causing fuel leaks and fitment issues. Like mine did. Then gas range. Mine has pulled 75 to 125 miles to the stock tank on this trip.
I have some motor work, dp system and ecu tune.
The 620 muti is a pile. Not enough power to pull itself out of its own ugly shadow. The 796 is crappy as well.
I have carbon wheels back at home for mine. But they are pretty good around traffic. I'm not a huge fan of wide'ish handle bars lane splitting. But I get over it. Even with the mirrors in, it still not like my paul smart.
Only other noticeable issue. Wind at speed. It can beat the crap out of you.
I'm usec to it now. Been riding from Phx to San Diego, LA, Santa Barbara up highway 1 to Ukiah. Just rolled 10k miles yesterday. Had 3k in November. So yeah accelerated wear. Anyways reversing my route next week. Up to 70mph is ok. 75+ the wind trys to blow you off the back.
