Wonder if cat will make a 9XX turbo twin to fit in the catalyst.

Thanks for finding this. Much appreciated. Funky looking piece of Carbon Fiber (my guess) for a front rear suspension arm!

That front rearcsuspension arm reminds me of the old fiberglass overload spring on the 2 ups. It actually worked very well

The fiberglass overload springs are still used on 2up yamacats. They've been used since the early 90's(on Cats), simple and affective.

Just sticking to what works. The last Kitty Cat,1999,had the same springs on the skis.

From an initial scan of the drawings.

The torque arm in this design is a tuneable multi-rate spring. The design is subtle, and it relies on the torque arm mounts being captive at both ends. It provides different values of spring rate based not only on displacement of the spring, but also distortion of the spring and on where the load occurs. This allows it to react differently to loading the front of the skid vs the middle or rear of the skid.

Take a fishing pole or any bendable rod, hold it out horizontal in front of you. Bend your hands inward such that you create an arc in the rod, that is one function, the other comes from distortion. Take the same rod, and without twisting your hands move one hand up and the rod takes on more of an S shape, that is the other function. In either case, when travel exceeds some amount the adjustable transition point kicks in and you get a second spring rate.
