I made a sway bar disconnect for my King Quad, that can be operated on the fly, using a bicycle locking brake lever and cable.. It's very tight quarters in that machine and quite out in the open on the CF Moto so the latter ought to be an easier build.
If the sumbitch '17 Zforce 800 Trail ever arrives!
Tried to attach a pic but I must not have enough posts to have the privilege.
Edit: What ya know, it did attach.

The anti-sway bars on these machines do not act as a torsion spring like some car and truck suspensions but rather they just link one side's A-arm to the other, with some 'give' in the outer attachment points.
The bar can be safely cut and a way of disconnecting introduced without affecting it's function. There must however be a way of keeping the bar in axial alignment. The bar is of good thick tubing material and if a collar such as Chuddly's diagram is used and it is of sufficient thickness to resist distorting and long enough to hold axial alignment, that ought to be a very economical way to get a disconnect. Mind you it will have the disadvantage of requiring the rider to stop and insert or remove a bolt.
By using bolts with a section of solid shank (not threaded right to the head) that are a good fit in their holes, and a using a thick enough collar, hole ovaling and introduced slop should not be a concern.
