I have a friend with an 04 LT. At certain highway speeds he could not release his hands from the handgrips without a severe wobble - dangerous. The local BMW dealer was diagnosing it and trying to resolve the issue, but BMW rejected the warranty claim stating the bikes were not designed to used without both hands on the grips.
The dealer did cover repairs under warranty. It took a couple of attempts. But, I believe he ended up with a new front wheel the first time - a later a new from tire as well.
I hope this helps.
