When I test drove my new RG Ultra before I bought it, the handgrips were too high and forward. So I had them turn the handlebars down a little and it was fine. I rode a couple hundred miles Saturday and about one hundred Sunday and I didn't have any problem with the bars. It wasn't much different than what I felt on my Ultra Classic.
It does run hot. But I haven't had stage 1 done yet. I notice that when I ride around town and get in traffic, the system that turns the rear cylinder off kicks in. Temps here have been in the mid 80s lately. BTW, you have to activate that feature because it is not activated from the factory.
