With a lot of twisty riding and hard breaking ~12K fairly normal, mostly highway then ~20K. Many people have had good luck with Lyndall's I did not, tried 5 different sets on my 2 bikes and they would produce a low speed squeal when coming to a stop. Went back to EBC's and no squealing.
I just swapped up my orginal brake pads at 29,00o and put on the lyndall pads and wow I can really tell a big difference from stock. It did take a few miles for them to break it.
