I have had a few of them, really depends on your style of riding and all that crap.
The HD was a blast, put 20k on it in two years. With the clip-ons and rear sets it was fun !
.
The Ducati was sexy, Monster 900, and that was about it, (at the dealer more than on the road)
The Bandit was totaly Kick ass, loved it, rode the piss out of it, it left in 3 boxes
If I had to do it all over again the HD is the bike of choice for just going out and about,
The Ducati was the bike to go cruze down town seattle and then park at starbucks for hours.
The Bandit was the all around bike, it was fast, ez to ride and just plane fun. I did blow a rod but thats a different story, and not the bikes fault in any way.. Redline is there for a reason, dont push it for days on end.
