My last set of Kevlar brake pads left me with 68% or greater of pad left after 27450 miles. I changed them only because the "warp" (wedge like wear) per Harley Davidson specs was exceeded. In addition, the rotors showed no wear from the pads. I am sticking with Kevlar pads. The D2Moto price was less than $20 for both the front and back sets of brakes and no shipping. I am very pleased and have recommended these pads to my peers.
