Just acquired a 95 CR80R for my son runs good, needs some maintenance items. I have search the internet to try and find out when and what the yearly changes were. Looks like 86 to 95 then 96 to 02 is a generation change. I am looking for a few things, one is a pipe and silencer. I can find fmf, pro circuit for 96 and newer. Was there frame changes? Just need some insite?
