Every regulator and rectifier does the same thing for each vehicle. The rectifier changes three phase AC to DC, and the regulator bleeds off excess current as heat. Doesn't matter if its from a Chevrolet or Yamaha.
On my 79 Suzuki, I went from a separate rectifier and regulator to a one piece R/R from a 2005 Kawasaki Ninja 500. The hard part was going from eight wires down to six, and the wires were all different colors. The wrong connection could fry the alternator, battery, wiring, or R/R.
If you can read a wiring diagram, any good R/R can work. If you want plug and play, it's best to stay with a Honda with the correct connector and wiring. Have you tried Ron Ayers for your R/R?
As for "heavy duty", what's that? More cooling fins? If you can get some airflow to the R/R, or get it into the airstream, it may last longer.
