funnily enough all the rear suspensions
back then except rm
were pox
yz490 cr500 were on a par with the kx
i remember trevor williams trying ohlins and white power on the bikes
but found standard shock worked better
i raced back then on these bikes
and like all the models you had to set them up
also there was not a lot of guys racing kx500s
back then it was when mr mx went 250 :'(
so these bikes were just kept for aussie title meets
in standard trim the motors were the quickest no contest
i also raced a 85 kx500 these were a great bike
like night and day over air cooled i still have one
in my shed its the quickest out of all my 500s
and yes the 83 and 84 are a cool bike and it doesnt really matter
but remember the other models were not much better
