Welcome aboard from Minnesota! Glad you've joined the fun. Didn't the Diavel just come out this spring? What made you switch?
Wow, that is a difficult question to answer. If I could, I would have kept the Diavel. It is one amazing machine. But I am not here to bore you with what makes it a great bike. I am instead going to say what makes the Harley great for me. Well I should say what I think will be great for me because I am a HD newb.
For starters as you all know the HD is going to be fun to personalize. The Ducati is very limited in that way. The HD is great for cruising and the Diavel is not really as good at that. My wife will be more comfy on the hog after I get a good seat for it. With the Diavel, there was no way to put a sissy bar on it. And one last thing, the HD has more chrome.
Cheers
