I'm a new convert to Beta but still have KTM's and Husbergs in the shop with the DDS clutch that I've come to really like, the Beta clutch works great but the pull is massive compared to the new DDS stuff, with the MM leaver you will get a pull that is as good or lighter than the new KTM's.
Another benefit is that it's short, the top fitting on the clutch line is kind of long and limits adjustment if you run a hand guard top clamp style mount.

Well worth the $$
