Actually, those descriptors of the KX500s were in comparison to my '98 steel framed iron-lung sieze queen. There's no need to compare them to an AF.
Yada, yada, yada, "those things suck, the KX500 frame is better, blah, blah blah." Yup, the AF is over-rated.
That being said, I wonder why the hot topic here is about the KX500 motor in the KX250 frame conversion? Better handling, stops better, so on and so forth. You just wish there was a Service Kawasaki.
It's good we can disagree and still like the pull of a big bore. If the CR500s didn't exist, I'd probably be on green.
