I got 65k out of my RK chain and sprokets before I traded it for a new bird. But it was less than half worn. Mind you I had a scott oiler installed with that chain compared to my first chain which was shagged after 35k which was lubed and maintained regularly.
Whereas with the scot oiler all I did was wash my bike and keep the resivour topped up.
On my new bird I have the scott oiler installed and I've done 20k and haven't even adjusted my chain other than the initial run in period. This is with doing track days and regular mountain runs.
Cheers
Chris
