Welcome Dan,
I too came from a 98 Ace Tourer to my RSV. That was one of the first things I noticed, other than the weight of the RSV. The heat down low can be mitigated by getting yourself a set of lower wind wings to push the heat away. And was already said, get some highway pegs to get your feet out into the windstream.
By the way, ,, you won't make many friends here by rubbing in the fact that you can ride year around while we're frozen and up to our @#&* in
