Actually, the clutch does use a friction point. It's a very fine and small friction point, but if you are very careful and let off the clutch very slowly you will see that it is smooth linear movement and not an on/off switch.
At least that's what I have noticed. Is there any details or statements that say it's an on/off switch or not?
my english is not very well...with the clutch (on off) i mean to enable or to disable....
yes you can see a smooth linear movement...sorry guys...
