i would like one, does anyone know a stockist in au?

 

They work very well, and they are worth fitting.
Not only for cornering improvement as some people think.
They help high speed stability as well.
Try MandM

I have one by Progressive and found does make a difference - and that is after I had installed good rear shocks and redone the front (springs and oil). Mine is a 1998 FLHT with an S&S 113 so it needed a bit of handling help --
