The rear shock spring on many of the new KTM's a dual rate. The White Power PDS system also has progressive damping. With the std set up it is very dificult to get the rebound working properly. Setting it so it works at low speeds means it is rebounds too fast at high speed and setting the rebound so it works at hirg speed means the rear packs down at low speed and kicks. A simple change to a linear rate Eibach spring makes a huge improvment.
