Single disc vs dual

I ride one of our shop bikes which is a 2007 with a single 13" PM floating rotor and PM 6 piston brake caliper.. The stock brake calipers on 2007 and early bikes are pretty weak IMHO so even though we removed one rotor/caliper the new setup brakes just as good as the original setup if not better. We also changed to a single disc style master cylinder which helps with the brake level feel. If you like the single disc look go for it and you won't be disappointed.

Are you sure? You may want to rethink your statement.
I'll agree that the tire meeting the road is ultimately how the bike stops, but the caliper, pads and rotor provide the necessary forces to the tire to stop the bike.
Reducing caliper, pad and rotor capacity will reduce stopping ability.

I'm comfortable with it. Read the rest of what I wrote, we're actually in more agreement than you realize. That said, for what the op described it will work. With a 13" rotor and 6-pot caliper, it should work quite well.

I have a 2018 RGS, I’m going to add a 21” PM Formula wheel. I have ABS as well. I want to do a single sided rotor with PM’s MegaBrake kit. I do believe that should make up for the second rotor as I as well live in a flat area with 90% of the time of just me on my bike. Would this mess up my ABS?

I haven't had a Harley that couldn't lock up the front tire with the single front disc. And foxtrapper is 100% correct that the tire is the determining factor in that case. In fact for most it is easier to modulate the brake with a single disc than dual as it takes more pressure on the brake lever thus easier.
According to a school in California just for braking the average rider that takes the course comes in only able to achieve 0.4 G's decceleration with their bike and leaves with the ability to get to 0.9 G's.
I will bet that most on here don't practice emergency braking each season with their bike and are more concerned with "Riding Like a Pro" and do figure 8's in the parking lot. Object avoidance and emergency braking are the two most important maneuvers that a rider needs skills and constant practice with.
Just my opinion.
