I'm considering the use of solid bar mount cones on my 98 KX250. The stock rubber ones and a second set of Neoprene units from Scott's performance have been weak at best. After a few falls, they became distorted and the bars would no longer line up correctly. Would I notice the change to solid mount cones in terms of vibration absorption? Does the rubber make a difference here? I'm open to suggestions here. Please advise. Also, anyone know where to get the solid units? Thanks in advance.
