Ok so over the winter I am planning on getting my Ninja 250 from trackday shape to racing shape. I am exploring rear shock options but so far have not found much. I have heard an SV shock can swap but the SV shock isn't great either. I know penske makes an awesome shock but it is just a tough pill to swallow when you are talking dropping almost half the value of the whole bike into a rear shock. Anyone have any experience or insight into this?
