Its easy really,
I got 110k on mine and nearly on 3rd set of discs.
If you want longevity and not so much feel or bite get bmw pads they are expensive but last for ever,
more feel and bite go for ferodos from steptoe etc. i use these with his discs and they are great particularly when hot.
I use a lot of rear brake dragging it in corners etc aftermarket can go in as little as 2-3k so i go with the bmw (adventure spec sintered) which are 3 times as much but get 3 times the wear rate.![]()
Cheers for the info interesting as I tend to ride similar to that !
