The ones you speak of may be better paid then the ones at the dealerships, but they too may have been told to keep quiet or loose their jobs. We all know that there is a nondisclosure contract that is signed stating that they will not give out information on upcoming models.
I'm not trying to defend the withholding of information just trying to understand it better why the information is being held. If it would cost me my job or perhaps put me in a situation that I might get sued for giving out information I might be reluctant to give out information also. 
I just think the heart of the problem lies within those that we can never directly contact.

Gary, those who don't speak are a bone of contention we've spoken of before here. Harley makes it incredibly difficult to really access some person. It's not their best thing.
The reps that are dispatched, however, are a different beast entirely. Some of the things they say regarding paint, engines, pitted chrome, the effect of changed parts on unassociated systems, etc etc etc is just beyond the pale. I disagree with you on the motive force of having to live within the confines of nondisclosure.
If someone simply told any one of us, "sorry, I can not answer your question." Or, "sorry, this is an issue under review and I am not allowed to do more than X and Y." Something at least direct. I can live with someone having to follow orders and toe the line. It's the direct misinformation or seemingly intentional incorrect information whose only purpose is delay, obfuscation or the attempt to move the burden of responsibility away from the company and on to the owner that is insulting. That it's not actually embarassing to them only bespeaks the character of those issuing the guidance.
