cut off date is actually a 1984 model
1985 cant be used unless it is unchanged from the
1984 model
main diff is disc brake everything else is the same
its funny though the cr 250 1984
uses the same front brake system
so technically you could put a honda 1984 front end on and it would
be legal
so work that out
they are designated 1984 models
i have a kx500 1985 i purchased in august 1984
but its an 85 model its the designated year that is legal unless it is unchanged :'(
