Mostly depends on your weight, no offense LOL. If your 150+ it'll most likely be worn past the service limit (19mm width). Ive seen a p150 with 12k on it but the girl must have weighed like 110 and the belt was almost like new. If you baby your bike off the line, it'll drastically increase the belt life, this is the hardest thing on the belt when the clutch engages HARD. If you have 10,000km it'd be worth opening it up with a spare belt and rollers, or even better sliders, at your disposal in the probable case that they are both worn out.
