When you did these experiments did you measure cable travel at all? Reason I’m asking is I’m interested is swapping my clutch to the Magura but want to see what the difference in cable travel will be compared to my aftermarket clutch lever assembly.A while back on another post I mentioned that I was going to use a Magura clutch lever assembly on my XS2. I also mentioned that the Magura had more cable travel. I knew it would increase cable movement, but had not really checked to see how much.
Since the Magura I had is going back on my X75 I ordered a new one. The only new ones I could find were split perches. Did find some old style ones on E-Bay that people thought were worth a fortune. I ordered a split perch like this one. Best price I could find.

In the other post 2M had mentioned a problem with our cables being a larger diameter than the Magura feral. Little more research and found this. Just what is needed to use a Magura assy on a 650.

The only good clutch cable I have is on my bike, did not want to test with a worn out one so I ordered a new Motion Pro cable. Never hurts to have a spare.
Time for testing. 3 clutch lever assemblies. New split perch Magura, old style Magura and a not worn much Yamaha. Going to check them using a short arm actuator and a long arm actuator. Also used the same grip on the handle bars for all the tests.

The test setup. Added a kick stand return spring to make sure the arms returned as far as the could.

Results of test below. Definite travel difference.
Short Arm Long Arm
Stock lever .095 .067
Old style Magura .120 .082
New split perch Magura .132 .092
The Magura could help if you are having disengagement problems with your clutch and you are sure everything is set up correctly. I'm going to experiment next riding season with the short arm verses the long arm worms using the split perch.
There is one disadvantage with the lever, it sits farther away from the handlebars than a stock lever. That's what gives it more cable travel. My hands are big enough it should not be a problem. I'm also curious if .132 of push rod travel is more than the clutch can handle. I put it on my bike and it feels OK with the short arm worm that is in the cover. Doesn't feel like it's coil binding, but I have not ridden it yet.
