Definitely recommend giving the folks at HHI a call for brake pads.

As far as other parts from HHI including 6 Piston calipers we offer them on our site at a discount. PM me if you are interested in a quote + proper lead time.

I have dual 6 piston HH calipers on Braking floating rotors on my 01 Dyna. It stops now!! It originall ycame with EBC pads, I was quite disappointed,allthough they stopped good, intial bite and feel where terrible and required too much lever squeeze.
They stayed on for one week, then where replaced with SBS #676HS. Much better and have lasted 40000klms with lots left.
If your looking for them, I found listed as replacements for 98-02 Buells.
Most general stops under normal riding are done with two fingers, and handful will lift the rear wheel off the ground on my 700lb DYna. I had to change to softer tire on front to get maximum braking, initally I used Dunlop 591, but they cupped very quickly under hard stops. I switched las year to Avon Roadrunners, no cupping, same ability. FWIW Fastrider 124

 

I really like HHI calipers, had a 4 piston on my 95 DWG & twin 6 piston on my 05 RKC with LRB gold pads. I switched the RKC to metal matrix floating rotors which helped braking more & almost completely eliminated brake dust on wheel. The pads are the same as a PM pad.
