Look forward to reading this review! 
Well after putting on approx. 500 miles on and off in the last four days mostly on the K1200 LT as I already knew what the HD was all about.
Here is what I found with the K1200 LT
PROS
A lot quieter, No valve train noise, could ride without ear plugs.
Great handling, so is my HD
After riding around will keep the Top Box and it does not affect handling, at least for me.
Great Wind & Rain protection, love the adjustable windshield, would change for a lower one.
Great Power, however so is mine with the 120R crate motor that hd-dude installed.
Great long distance bike, so is my HD.
Not everyone has one.
CONS
Engine noise will take getting used to, people would say nice bike but it doesn't sound like an HD, guess what bikes they own
Five speed transmission
You want to keep up the engine revs up for best performance, in the 4500 rpm range, will rev up to 8000 rpm
Radio and speakers suck
No WOW factor, again everyone would say nice bike, but then comment the HD is way nicer looking.
I made a few inexpensive mods, added RT type mirrors, the fairing mirrors suck. Removed the 6 disc CD changer and Added the AUDIVOX DICE iPod interphase can control everything through the factory audio set up. Decided against removing the Tour Pac, bike not to top heavy for me, may still change from pegs to floorboards, not sure yet don't want to lose cornering clearance.
Still not 100% sure if I will keep, I'll see after a 1,200 mile trip.
