I did the steering head bearings on my Dakar at 27K. I am hoping I get the same run out of the F8 as I had with the Dakar, they are an awesome motorcycle. They look the goods with 606s on them but I found the rears wore out in 4K. I ended up running D605s on the front and K60 Heidenau's(140/17) on the rear and had great grip and awesome mileage out of them. Awesome bike.

Time don't matter to me,
Cause I'm a thousand miles from nowhere,
And there's no place I'd rather be!!
