Symon is correct.
When i replaced the clutch on my older GQV, i asked the mechanic same question. He said it depends on your driving habbits. If you drive in lots of traffic or terrain that causes the clutch stress, it will need replacement earlier.
He also said he had cases with vehicles with 50k km that needed clutch replacement.
It happend to me when the milage was on 70k km. Was in traffic and started to smell something burning. Managed to get home, but on my next drive to work again the same burning smell.
