Mark, I thought I had read a while back that Honda(I think it was) was working on a water-cooled cruiser that had it's radiator hidden just behind the engine and in the sidecover area, and it had some sort hidden duct work under the gas tank which would allow airflow to it, and that airflow would exit right next or in front of the rear wheel.
(and BTW...Benelli sort'a "borrowed" that underseat radiator idea from a certain Kiwi motorcycle design genius known as John Britten...may he rest in peace)
