125 expected clutch life

[TheInternet]

Looking likely that I'll need to replace part of my CG 125 gear selector at some point soon and wondering if it is worth also replacing the clutch plates/springs whilst I'm in there.

Is there a guideline to the expected clutch life on a 125? This particular example has not had a tough time.

Bonus question: Is it necessary to replace the metal plates or just the friction plates? At present the clutch action is gorgeous butter, Lurpak at room temperature.

Clutch life depends on use and the user. Really hard to tell. You may take the clutch apart and check the plates and springs (springs should have a certain length/height, plates thickness).

Normally you replace the friction plates. Once again, check the thickenss of the steel plates as well. I'd imagine both being cheap for the CG, so IF I decided to do it, I'd replace them all + new springs.

IF the clutch doesn't slip it's still alright, no need to replace it.

**Haynes or the service manual to your motorcycle should tell you the minimum thickness of the plates and length of the springs.
