1981 650kz csr ?

any where to find info on this bike --performance wise --say an old advertisement from a dealer --with specs like weight -gear ratio's --and what kind of bearings are on the crank --any info would be great --i think i'm going to be buying 650four's bike in the classifieds---always like the style of the older muscle bikes --and so far the 650 is fitting the bill ---

Look in the Filebase under the KZ information tab at the top, and in the Links section on the right.
