I've got brand new Ohlins (conventional, not piggy back) that will bolt straight onto that (or any other PE for that matter)
A couple of sets availables.
£300 a pair (new not recon or rebuilt etc etc. They are new. Box has the Swedish air still inside them!)
Postage to Oz, no problem.
If you want that kind of money for a PE, might as well treat it to some decent shocks!
420mm C - 2 - C by the way
(and red rocket lengths are on the way....)
