Book says 24,000 for belt off memory, and I suspect most will go well beyond that (mine is currently at 32,000 - has cracks on the inside, but there's no depth to them and that's not a particularly structural part of the belt).pxc-in-japan wrote:As I intended to swap the belt, rollers, etc at about every 18,000 - 20,000 kilos anyway
I wouldn't worry about variator rollers unless it "gives you a sign".
My personal philosophy (apart from oil changes which I do every 4,000km) is to just give the bike regular inspections and to not "over-service it" - I think most scheduled components will give you plenty of warning before they reach the end of their useful lives.
