It varies depending on brand. It could be anywhere from 3.55-3.85mm

I appreciate!! The bike has 75 000km with original clutch!! All is new, except the clutch and I’m very surprised about the « wear » of this one !!

Be sure to replace the springs.  Stock work fine.  Aftermarket springs tend to be higher tension, which can tire out your hand.  Also, lube or replace the cable with OEM.  You will be amazed how smooth the clutch feels with a new and lubed cable.

You should post the dyno results. I am thinking around 70HP at the wheel.
