I test rode a new black Indian Chieftain in Daytona and fell in love with the thing! Its not a small motorcycle by any means, but on the Indian Forums the tall guys say it feels a bit cramped to them, but at 5'9" it fits me perfectly.
It handles great and makes a boat load of power throughout a broad range of rpm, no bogging, pinging or hesitation at all. It absolutely feels like a much smaller and lighter bike than it is, but not in a bad way at all. The stereo doesn't suck either!
I hate to say it, but the only problem I would have is triking it. It's such a perfect motorcycle I'd be tempted to keep it as a two wheeler, but if anything could convince me to convert it, it would be the Hannigan conversion.
