My bikes have low cost pads from DSS.
My K6 has dual front brakes, both rotors from DSS that work fine.
My K2 has stock K6 single rotor.... huge difference... this is not a brake
But its rear brake work better, old Honda shoes.
I have used SBS before. Pads had thick layer of paint on outside I had to sand down completely to make pads to move smooth in caliper while braking.
