What year is your model?
On 2016+ models the clutch can misbehave from around 25000km. Some have replaced it several times to no good results.
My gut feeling is that BMW have changed the clutch bell to a newer cheaper metal and made the clutch pads softer to compensate so the bell does not wear too fast. But overall the result is not good - this is the weakest part of the C650 line.
If you do not have issues, enjoy.
I have had a lot of tries with Dr. Pulley's HiT clutch and found the "happy formula" but that requires you custom order a weaker BL6-5.2kg clutch spring set, possibly at same time as you order HiT. They can include springs for free. Otherwise as it comes, there will be a larger "rpm gap" for clutch engagement - this is bad for my mountain pass riding as I end up in neutral in almost every turn which sucks for handling and confidence.
It is best to start wearing HiT with those right springs from new as "bad combo" can cause excessive beating and vibrations and can damage clutch and other parts (bearings) in the transmission.
My HiT have had a run of about 60K kms and needs service - new spring set and maybe the spring dampers as well as there is a lot of loose noise at idle, especially after cold start. I might be looking to install the stock clutch meanwhile - don't know if it will be any better after deglazing and re-springing or not...
