Just under 50K on mine. Don't get me wrong, there's always room for improvement and I've had some mechanical problems. I still haven't ridden another bike that is as good "all around"* as this though. I'm constantly amazed by how marginal the advantages of bikes dedicated to one particular task are over the F8, relative to how massive a sacrifice they make in the other areas.
* I want something I can:
Filter like a loon through city traffic on.
Fit sportstouring tyres to and trouble the sportsbikes on a track.
Fit knobblies to and go greenlaning or even get round an Enduro on.
Ride for 8 hours at a time without feeling any more fatigued than if I'd done the journey in the car.
Carry an 8' Christmas tree and/or a week of shopping on it.
The usual answer of course would be to own several bikes, but the F8 means I don't need to.
I like my bike because I can overtake 4x4s down farm tracks with a week's worth of shopping on the back.
