Ordered some replacement pads for my 1400 custom from a local Non guzzi shop. They got organic ones even though I told them it had stainless rotors. I'm pretty sure the oem's are sintered . I like the thought of less rotor wear but how long can I expect these to go on such a heavy rig? No return policy on special orders so I think I'll run them, or should I not? TIA, dave
