Just my pence worth usualy crap.

in superetards the bikes can suffer lots of chatter and after trying dialling it out with suspension the best things that worked were, 16.5' front lower tire pressure and then off set triple clamps -4mm and last better springs, maybe old ones were worn and tired.

The tyre profile has a larger side wall to soak it up (in theory) and to all purposes helped.

What size tires are you using? allso when was your suspension looked at?

Last thing for me would be chassis set up inc all your ride heights and preloads especially the back, I learnt more from Mr Matt about suspension than i could ever soak in. He was good enough to help me years ago and it helped me understand that bike balance is important.
