that would depend on how the bike is ridden etc...
I got about 11,500 on the stock pads, the bike currently has 28k. so the ferodo's are at 16,500 and are not even 1/2 way gone.
and I've actually heard from the mouths of guys who do a bunch of track days and races that EBC is not all that good.
my brother put some EBC pads on his cruiser and they were gone after 9k.
Ferodo is what Graves Yamaha is using on their bikes.
