Hello John,
Yes this is a magura,from a 300 ktm.The case has been machined to accept the magura slave cylinder.DoldGuy is right about the easypull,it just makes for alot different feel.When you lenthing the arm it will make it easer to pull,but then you have to pull the lever further to disingage the clutch.This will make the clutch heat up a lot faster.This is why i had to do something different.It cost to have this set up,but nothing you do to to the cable setup will ever work the way this will.I ride a lot of tight woods,so this was a must have for me.I can abuse the clutch all i want it it always feels the same,plus the pull is very light.I have this on two of my bikes,never had to do anything to it but change the fluid for more than ten years.I could never go bake to the cable after using this.
