Ian, my '95 is a Dyna Convertible not a Lowrider. I haven't measured it but it's way taller than my America, taller than the Bonnie and pretty close to an '06 Tiger's seat height (that's the only one I've ridden to compare with).
So, yes, it's not your usual Dyna...short 29° neck rake, mid pegs instead of forward controls, lots of clearance and with the after-market cam, pipes and air cleaner lots of power. I sort of suspected the new Dyna would give the results Al posted with it's longer rake on lower profile and tame twinkie engine. My main objection is the rubber mounting system where they clipped Erik Buell's nice three point design to save money.
And, like I said before, my butt chooses the Triumph nine times out of ten :-)
