Wow those ramps are steep compared to what I've seen on my STM and on Yoyos. I really want to put an STM in my 2015

If you can Sigma Slipper Clutches in the US, they're arguably the best. Ran by Neil Spalding who is a big player in Moto GP technology.

I Ride: Track Preped 07 ZX6R
I'm going to spec my factory clutch to the race manual recommendation... different clutch plates, clip a spider spring or two for easier action... (Found this on my blown race prepped engine disassembling it for parts...) shim up the clamping springs 1mm for a little more clamping force instead of the shorter spring keepers the manual talks about... All of this costs hundreds of dollars less than an aftermarket slipper, and if you need parts, they'll probably be at the track.

Here's a Link To Another Thread with some input from Enro. Saw a video of him murdering 1000's coming into a corner on his race prepped bike with the kawai slipper clutch, but i cant find it at the moment.

I didn't realize this but the 13+ zx6r has a different clutch style with positive engagement using less springs and having a lighter clutch pull.

Is the 13+ adjustable?

13+

I'll answer my own question.

Already posted on another thread but might as well put it here too

-----------------------

I was looking up info on the 13+ zx6r slipper and it's different than the 07-12 which means it's no longer "race adjustable". The race kit manual has different specs to modify the slip which are not applicable to the 13+. So, again, no longer adjustable but has a much lighter pull effort.

Here's how the 13+ clutch looks





2013 Kawasaki Ninja ZX-6R First Ride - Motorcycle USA

The Ninja’s drivetrain also received some improvements in an effort to make it friendlier to ride on the highway. The big news is the fitment of a clutch sourced from Japanese company Fuji Chemical Company. The wet-style clutch is similar to the Ninja 300‘s and features a more simple design allowing for fewer mechanical parts and less weight (over 1.5 pounds lighter than the old unit). A cam system pushes the clutch plates together when the engine is loaded (acceleration) and apart during deceleration. This allows for fewer clutch springs (from six to three) and wispy, one finger light lever pull. While this facilitates a degree of back-torque limitation (rear wheel chatter) conversely it can no longer be deemed a true tune-able ‘race-style’ slipper clutch.


Here's a picture of the 07-12 zx6r (ramps visible, pretty steep too) which was fully adjustable.

hmm. Let me know how the specing out the stock one works for you. I would be interested in the cost and if it gives better feedback.

I would be more than glad to let you know if anyone had a donor 09-12 clutch lying around for experimentation

Doubt it though.

I never realized there were so many aftermarket slipper clutch options.

Another one: EVR CTS Clutch
