I'm a graphics guy (I like the sport bikes and graphics; I think bright colors like the wing in yellow or orange are great) and haven't found anything I can think of to do to the LT and I'm not big on the muted palette BMW uses. I'm not sure which of these I like best, but it is your bike - if one of them makes you happy and you like the way it looks, go for it. They are kinda neat, the way you;ve designed them into the vents. I think there is a beginning there. Maybe a less contrasty color, like a similar gold or something. Just a thought.
Good luck with it.
