    Ah, now that we see the other side, yes, that is an abortion. That's just not good engineering.
    In fact, it may be the opposite.

    You can defintely see the inner second link. I can only assume the chainstay link is to simply add lateral stiffness.

    so the shock actuates on the bottom "arm" while the upper "arm" is for lateral stability.

    and the shock has a remote lockout or damping adjuster.

    MMmmmm.

    it's a sinlge pivot, with an insanely complicated linkage for driving the shock, Nick.

    Its very hard to work out what is going on there. However if it is like any other Sunn out there the bike will run like a beauty for 6 months and then something will crack (sunn vertik - seatstay, sunn radical - chainstay, sunn radical - headtube!).

    It is very similar to motorbike rear suspension and the banana swingarm that you Suzuki used to use on the RGV that evolved into the current swingarms used today for torsional strength. Don't understand purpose of the lower bars though.

    The RGV's arm was just a funny shaped conventional swingarm though... Nothing out of the ordinary about the suspension design, which is what makes this thing stand out. The arm itself functioned exactly the same as the old one, it just had different a different linkage and created clearance for them to move the expansion chamber on the exhaust.
