2014 super glide with abs and stock hd pads. It buzzez too

No noise from my 16 Dyna Low Rider with standard factory pads

Maybe I'm reading too much into this but it seems from the comments in the thread that more of the earlier bikes than later bikes had/have buzzing brakes, maybe Harley changed the pads or brake design to fix the issue?

No noise.  2018 Fatboy.  

Geoff the only "design" difference i am aware of is on the tourers, they now have a linked brake setup, get on the rear brake first and they activate a very slight application of the front. The system unusual in that it electronically adjusts the overall proportion of linking, both front to rear and vice versa, based on how the rider is using the brakes. If you’re an expert braker and applying appropriate amounts of front and rear pressure, Reflex will assist you very little. If you have poor technique, Reflex will assist you by adding brake pressure where it can most effectively be used, shortening stopping distances and enhancing safety. If, for example, you stand on the rear brake in a panic situation, the system keeps the rear from locking up and automatically applies front pressure. The computerized system disables linking at speeds below about 30kph so that maneuvers at parking-lot speeds can be conducted using the rear brake only. 

2015 Fatbob no noise

2016 Slim 103...No noise.

I always thought the buzzing came from the rotors - specifically waved rotors.

My 15 street bob used to buzz under braking as well but the 2016 slim has no noise
