One detail I noticed was on the pegs. There's some sort of fancy little metal peg sticking out of the end of the pegs underneath. It's obviously sacrificial, so you won't actually drag the peg on the ground. Now on the Triumph Floorboards, for example, it's a cheapo coupling nut available at any hardware store. Easily replaceable. But this Harley bit was definitely unique to these pegs and probably cost $20 apiece to replace. Typical HD.
