When I moved from Portland, OR to Virginia Beach, Virginia last March, I went to my local BMW dealer and purchased a Canyon Dancer Bar Harness. Loaded the bike in the back of my Chevy Silverado and after carefully positioning the bar-harness over the grips to make sure nothing could twist or bind, I then synched it down on each side with two rachet straps with just enough tension to keep the bike vertical and pressed against the front of the truck bed. I then used two more ratchet straps from each side of the front wheel to the same hooks in the floor to keep the wheel straight against the front of the truck bed. This keeps you from needing to use excessive tension on the straps to the handle bars. Frankly I was more concerned about snapping off a handle bar than I was possibly damaging a heated grip.
With a short bed truck I had to leave the tail gate down so the only other thing I did was use two more ratchet straps through and around the rear tire to hold the rear end of the bike in the center of the bed. 3200 miles of sometimes seriously rough highway later I'm in Virginia, the bike doesn't have a scratch and the heated grips work just fine.
I've trailered the bike a couple of times since using the same tie-down method without any problems. However my new local dealer made the same comment as others have that a bar-harness will damage the heated grips. All I know is that it works for me and so far it's the safest, easiest method I've found to tie-down my bike when needed.
